Add a no_driver ironic driver type

Enabling this driver type ensures that the no-console, no-raid
and no-inspect interfaces are enabled so that they can be later
configured on a per-node basis if required.

These interfaces are useful to have enabled at the same time as
driver specific interfaces such as idrac or ilo in order so that
managment of specific functions can be disabled if required.
