This patch introduces a new category called "suite".
A suite is a collection of workloads.
Each workload in a SuiteResource has a tag that can be narrowed down
through the function with_input_group.
Also, the set of input groups can be seen through list_input_groups.
Added unit tests to test all functions of SuiteResource class.

* tests: Remove large files from resource specialization tests
These tests were downloading resources (but not actually using them) to
ensure the `obtain_resources` function returned the correct
specialization and was parsing the data correctly. As these resources
were never used, this patch removes the downloading of large files in
this case, replacing them with smaller binaries.

* tests: Rename 'looppoint-json...' example specailization
Appending '-example' to the end avoids any name clashes.
'looppoint-json-restore-resources-region-1' shares this ID with a real
resources in gem5 Resources.

* tests: Remove disk image download from Workload Checks
This download is big and unecessary (the workload is never run as part
of the test). This patch changes this test to instead download a small
binary in it's palce (again, this does not matter as this is never
actually run as a disk image).

* tests: Update IDs in Pyunit Workload checks
Some of these IDs clash with real workloads/resources in gem5 Resources.
To avoid any possible clashes or confusions, all the mock
resources/workloads in this suite of tests has been renamed with
'-example' appending on the end of the ID.

This patch includes several changes to the gem5 tools interface to the
gem5-resources infrastructure. These are:
* The old download and JSON query functions have been removed from the
downloader module. These functions were used for directly downloading
and inspecting the resource JSON file, hosted at
https://resources.gem5.org/resources. This information is now obtained
via `gem5.client`. If a resources JSON file is specified as a client,
it should conform to the new schema:
https//resources.gem5.org/gem5-resources-schema.json. The old schema
(pre-v23.0) is no longer valid. Tests have been updated to reflect
this change. Those which tested these old functions have been removed.
* Unused imports have been removed.
* For the resource query functions, and those tasked with obtaining the
resources, the parameter `gem5_version` has been added. In all cases
it does the same thing:
* It will filter results based on compatibility to the
`gem5_version` specified. If no resources are compatible the
latest version of that resource is chosen (though a warning is
thrown).
* By default it is set to the current gem5 version.
* It is optional. If `None`, this filtering functionality is not
carried out.
* Tests have been updated to fix the version to “develop” so the
they do not break between versions.
* The `gem5_version` parameters will filter using a logic which will
base compatibility on the specificity of the gem5-version specified in
a resource’s data. If a resource has a compatible gem5-version of
“v18.4” it will be compatible with any minor/hotfix version within the
v18.4 release (this can be seen as matching on “v18.4.*.*”.) Likewise,
if a resource has a compatible gem5-version of “v18.4.1” then it’s
only compatible with the v18.4.1 release but any of it’s hot fix
releases (“v18.4.1.*”).
* The ‘list_resources’ function has been updated to use the
“gem5.client” APIs to get resource information from the clients
(MongoDB or a JSON file). This has been designed to remain backwards
compatible to as much as is possible, though, due to schema changes,
the function does search across all versions of gem5.
* `get_resources` function was added to the `AbstractClient`. This is a
more general function than `get_resource_by_id`. It was
primarily created to handle the `list_resources` update but is a
useful update to the API. The `get_resource_by_id` function has been
altered to function as a wrapped to the `get_resources` function.
* Removed “GEM5_RESOURCE_JSON” code has been removed. This is no longer
used.
* Tests have been cleaned up a little bit to be easier to read.
* Some docstrings have been updated.
Things that are left TODO with this code:
* The client_wrapper/client/abstract_client abstractions are rather
pointless. In particular the client_wrapper and client classes could
be merged.
* The downloader module no longer does much and should have its
functions merged into other modules.
* With the addition of the `get_resources` function, much of the code in
the `AbstractClient` could be simplified.

This patch makes changes to the stdlib based on the gem5 Vision project.
Firstly, a MongoDB database is supported.
A JSON database's support is continued.
The JSON can either be a local path or a raw GitHub link.
The data for these databases is stored in src/python
under "gem5-config.json".
This will be used by default.
However, the configuration can be overridden:
- by providing a path using the GEM5_CONFIG env variable.
- by placing a gem5-config.json file in the current working directory.
An AbstractClient is an abstract class that implements
searching and sorting relevant to the databases.
Clients is an optional list that can be passed
while defining any Resource class and obtain_resource.
These databases can be defined in the config JSON.
Resources now have versions. This allows for a
single version, e.g., 'x86-ubuntu-boot', to have
multiple versions. As such, the key of a resource is
its ID and Version (e.g., 'x86-ubuntu-boot/v2.1.0').
Different versions of a resource might be compatible
with different versions of gem5.
By default, it picks the latest version compatible with the gem5 Version
of the user.
A gem5 resource schema now has additional fields.
These are:
- source_url: Stores URL of GitHub Source of the resource.
- license: License information of the resource.
- tags: Words to identify a resource better, like hello for hello-world
- example_usage: How to use the resource in a simulation.
- gem5_versions: List of gem5 versions that resource is compatible with.
- resource_version: The version of the resource itself.
- size: The download size of the resource, if it exists.
- code_examples: List of objects.
These objects contain the path to where a resource is
used in gem5 example config scripts,
and if the resource itself is used in tests or not.
- category: Category of the resource, as defined by classes in
src/python/gem5/resources/resource.py.
Some fields have been renamed:
- "name" is changed to "id"
- "documentation" is changed to "description"
Besides these, the schema also supports resource specialization.
It adds fields relevant to a specific resource as specified in
src/python/gem5/resources/resource.py
These changes have been made to better present
information on the new gem5 Resources website.
But, they do not affect the way resources are used by a gem5 user.
This patch is also backwards compatible.
Existing code doesn't break with this new infrastructure.
Also, refs in the tests have been changed to match this new schema.
Tests have been changed to work with the two clients.

This patches does the following:
- Adds 'SimpointResource' which encapsulates Simpoint data and
functionality. It replaces the old 'gem5.util.simpoint.SimPoint'
class. Simpoints can be loaded from gem5-resources using the
`obtain_resource` function.
- Adds 'SimpointDirectoryResource'. This inherits form
'SimpointResource'. While 'SimpointResource' takes raw Simpoint data
via parameters, 'SimpointDirectoryResource' assumes the data exists
in files, in a directory.
- Updates the
"configs/example/gem5_library/checkpoints/simpoints-se-checkpoint.py"
and
"configs/example/gem5_library/checkpoints/simpoints-se-restory.py"
example files to utilize this new Simpoint resource classes.
**Note**: While the old "SimPoint" class
("src/python/gem5/util/simpoint.py") is marked as deprecated, it may be
difficult to utilize given updates to the APIs in the gem5 stdlib Cores
and Simulator modules.

This patch allows for the "version" field in the resources.json file to
be `null` (translated to `None` in the Python JSON package) or not
declared. In this case the resources.json file will be used regardless
as to what version the gem5 binary is set. This is useful for testing
purposes.
Tests have been updated to utilize this where possible.

This commit specializes the Resource class into specific sub-types.
The `Resource`, `CustomResource` and `CustomDiskImageResource` classes
have been deprecated in favor of the `AbstractResource` subclasses.
Custom Resources can be created via the resource specialization
constructor. Resources can be obtained via the gem5-resource
infrastructure with the `obtain_resource` function.
Fully implemented:
- DiskImageResource
- BinaryResource
- KernelResource
- BootloaderResource
- FileResource
- DirectoryResource
Partially implemented:
- SimpointResource
- CheckpointResource
While the schema of the resource.json file has changed, efforts have
been made to ensure backwards compatibility is maintained during this
transition.
Tests are included in this commit to verify this feature works as
expected.
**Note:** The Simpoint tests are disabled in this commit, to be
reenabled when Simpoint resource specialization is fully incorporated
