Users:
/users
is a GET only call that only READER users can access.
It takes an optional ?suggestion=<issueName>
argument that represents which issue breakdown you'd like to see across all users.
Response code is 200 and either a JSON list of all usernames available on the cluster or a mapping of usernames to some number representing the parameter issue requested.
Response code of 403 means you are not authorized to view this endpoint.
For example: /users?suggestion=emptyFilesUsers
will return a mapping of user names to the last count of empty files found owned by each user.
