Add in new targets to handle bmc resets while host running

The point of this new target is to support getting
the systemd targets which boot the host into the
running state (without actually running the associated
services) when the BMC is rebooted and the host is
up and running.  This will ensure that systemd
and its targets match with the state of the system
without affecting the running host.

This commit will run the new target but nothing will
happen yet due to the discovery service being a noop.

Once the application is in for the service to call,
it will be added to the service which will enable this
new host running with bmc reset support.
