[Openstack-operators] New services disable reason

Our install is still quite small and we take the risk of hitting that
compute node whilst the service is starting,  but we haven't actually
encountered that yet (probably a user base size issue) ...

IMHO, having a reason why stuff is disabled avoids hours of confusion and
trying to find the person who 'did it'.

In terms of keeping track, I'd have thought that the dashboard admin panel
can show you service states and I'd expect a disabled service to say
'disabled', but again we don't even use this feature at the moment.

+1 from me :)
