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. Change-Id: Iba6dc9a480f5805042602f120fc84bdc47a96d55
