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
