> 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)
