So do you think the double-check is too much?  Can we just go with the non-host variant of
the method for server-based tasks?  That comment is in a block that happens when the first
call returns a null/zero-length list.  I'd prefer just the one call without host.

Yes, right now the hack is to just pick any host.

ServerActionScheduler and db accessor - can you please review those parts?  This is all part
of the whole "server action on ambari when it's not in the host table" issue.  It's easier
for now to work around it then add ambari to the host table at install time (we need buy-in
at a higher level for that.  read:  Mahadev).  I added a comment that should get special attention
in ServerActionScheduler.doWork().

so a request for a Stage was bringing back all tests.  My unit tests passed and accessing
the endpoint looks good, but please check it out if you have a deployed cluster.  The fix
that Rob is looking at will be important for manual stages to work properly.  (My no-op was
failing to become PENDING, stuck as QUEUED).
