restart two namenode and two zkFailoverController services using REST API

[#1]

I am running into an ambari 2.2 bug where both namenodes go into standby mode. The resolution for this is to first stop both the zkFailoverController services and then stop both namenodes and then start them back up in the same order after which one namenode is active and the other standby. My question is how do I reference the individual zkFailoverController and namenode services in the REST call as I have to issue a total of 4 + 4 calls to stop and start them.
