Merge pull request #159 from bkearney/bkearney/5597

Fixes #5597 - Exposes new data in the repository-set info command
Fixes #5729 - content-host lookup by uuid

Commands info, create, delete commands expect a uuid as the id.
Currently searchables for systems are resolving the db id, so
the commands can not find the system by db id. This fix allows
all systems searchables to obtain the uuid as the
id.
