``upgrade_levels.compute`` is accepted, that allows automatic determination
of the compute service version to use for RPC communication. By default, we
still use the newest version if not set in the config, a specific version
if asked, and only do this automatic behavior if 'auto' is configured.
if asked, and only do this automatic behavior if 'auto' is
configured. When 'auto' is used, sending a SIGHUP to the service
will cause the value to be re-calculated. Thus, after an upgrade
is complete, sending SIGHUP to all services will cause them to
start sending messages compliant with the newer RPC version.
