Instead of trying to infer the type of the self hosted tests in each of
the driver scripts (inconsistently...), set one of the following
variables to "true" in the workflow:
VM: tests run in a virtual machine.
EPHEMERAL: tests run on an ephemeral virtual machine.
PERSISTENT: tests run on a persistent virtual machine
REMOTE: tests run on a physical remote host.
EPHEMERAL VMs can have multiple instances of any given VM can exist
simultaneously and are run by a runner pool. The other types have a
dedicated runner instance and can only run a single test at a time.
Other settings:
SSHFS: We need to sshfs mount over the repo so the workflow can collect
build artifacts. This also implies the tests must be run over ssh.
DEBUG_ACTIONS: enable "set -x" in scripts for debugging.
