supported args shoud be '--list', '--host <hostname>'
--list should return a json list of all the supported groups

--host <hostname> should return a json list of all the hostvars for the specified hostname

optionally return a json body with "_meta" and a list of all the hostvars for all systems
(how do you call the above? --host or --list or what?)
    ansible does a --list first before doing a --host, probably to get the members of the group you're calling so it can then call them with --host
    the --list output body should have _meta.  then ansible will use all those values instead of using --host for each one
    --host is ignored entirely if _meta exists
