API to fetch list of hosts without full host details
Description of problem:
A couple of users have expressed interest in a "host list only" API. This would be useful when scripting and looping over lots of hosts. If it took the same params as the existing /hosts api but returned only the host ID and hostname, that would be ideal.
There are a performance issues with the existing /hosts API call that are being addressed1; however even if it was lightning fast, a more minimal result set is still useful for scripting.
This is similar to Spacewalk's listActiveSystems call2 which does not return system details. The RFE came about from users with spacewalk scripts that run much slower after porting to Katello.
