> Use case:  When ambari node renamed, agent is not running on old name and as a result all the components are in UNKNOWN state.
> In order to remove component from the "old" named node, it status needs to be changed to MAINTENANCE, which is not possible in current implementation.  Want to issue following:
> {noformat}
> PUT /api/v1/clusters/c1/hosts/host1/host_components/GANGLIA_MONITOR {"HostRoles": {"state" : "MAINTENANCE"}}
> DELETE /api/v1/clusters/c1/hosts/host1/host_components/GANGLIA_MONITOR 
> {noformat}
