> This api takes in query and instead of failing fast on the first error, puts the best
effort to delete all requested hosts. Response should be json object which has deleted keys
and keys which failed to delete with exception.
> Sample API calls:
> Delete all host components on a set of hosts:
> {code}
> Request:
> curl -i -uadmin:admin -H 'X-Requested-By: ambari' -X DELETE http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/host_components
-d '{"RequestInfo":{"query":"HostRoles/host_name.in(c6401.ambari.apache.org,c6402.ambari.apache.org)"}}'
> Response
> {
>   "deleteResult" : [
>     {
>       "deleted" : {
>         "key" : "c6401.ambari.apache.org/HIVE_METASTORE"
>       }
