Comment 3 for bug 1584926

To be clear, this "fix" (miniture feature in disguise?) would potentially introduce a few new operations:

 - <nodes|machines|devices|rack-controllers|region-controllers> count
   * could really apply to anything in the system
 - nodes summary
   * prints a summary of object counts per node type
 - machines summary
   * prints the result of the three queries you asked for

The "summary" name on both endpoints is up for debate.

Also, the behavior is up for debate - I think it might be cleaner to have 4 separate APIs - one for the summary of node/type counts, and one for each requested "report"-like query.

Any thoughts you have would be appreciated.
