The "action-run.sh" action replaces inline scripting in the Vagrantfile.
The major improvement is this script runs an infinite loop and
configures the runners to be ephemeral. This means they cease to exist
after a job is complete. The script then cleans the VM workspace and the
loop restarts by configuring and setting up another runner. This means
our VMs no longer accumulate files that eventually lead to the VM
running out of space.

There are two places self-hosted runners can exist on GitHub:
1. At the level of the repository: In this case the runners can only be
used by that repository and runners can only be distinguished from one
another by labels.
2. At the level of the organization: In this case the runners can be
used by any repository in the organization, thus increasing their
versatility. In addition to labels, runners in the level of the
organization can be organized into groups.
While we do not use our self-hosted runners on other repositories, there
may be future use for this, so we might as well enable it now.

Having two types of GitHub Action Runners has not yielded much benefit
and caused confusion and inefficiencies. This change simplifies things
to having just one runner with 8-cores and 16GB of memory. It is
sufficient to build gem5 and run most simulations.

This reverts commit 0249d47acc,
https://github.com/gem5/gem5/pull/271.
This solution doesn't work. GitHub runners pull the images they need at
the start of job (i.e., all the images they may need for each step).
They then create the containers later, at the step they are needed.
This solution therefore breaks in the case a cleanup happens during the
running of a job. I.e., a `docker system prune` happens after setup,
therefore deleting all the images, then the job tries to use one of the
images during a step.
This crontab solution may work if we can only do it when the runner is
in an idle state. Whether this is possible is unknown.
