[jira] [Created] (AMBARI-4419) Add Passive State for Service, Host, HostComponent

Nate Cole created AMBARI-4419:
---------------------------------

             Summary: Add Passive State for Service, Host, HostComponent
                 Key: AMBARI-4419
                 URL: https://issues.apache.org/jira/browse/AMBARI-4419
             Project: Ambari
          Issue Type: Task
          Components: controller
            Reporter: Nate Cole
            Assignee: Nate Cole
             Fix For: 1.5.0


Add ability set a new state on Service, Host, HostComponent - a Passive State.

Passive State is used to maintain control of a unit in Ambari, but skip operations that include an item.  Examples:

* If a Service is Passive, a call to restart all Services should skip a passive one.
* However, said Service can be acted upon, if it is a direct target.
* A restart of a Service will ignore Hosts that are Passive.
* A restart of a Service will ignore HostComponents that are Passive.
* Rolling restarts do not affect items that are marked Passive

Passivated items will not generate alerts (that will be filed and tracked separately)
