> After resolution for https://issues.apache.org/jira/browse/AMBARI-6698, supported custom command for the service component is available via API. 
> Custom action subscribed to a component and available in the API should be shown under component dropdown action menu.
> *Exception:* decommission and recommission actions will be the exception where we show the custom command on slave component of the service instead of the actual component on which the command is subscribed in stack definition and eventually executed. 
> *Note:* If a master component has the max limit for cardinality of more than 1 and has the custom command affiliated to itself then find the number of hostcomponents installed for that component in the cluster and if it's greater than 1 then find the active host component and only enable the link for custom commands on active component. 
> If there is no active component even though there are more than one master component installed then show the custom command link on all master components (this specific requirement is to support the scenario where a component can have multiple instances in the cluster even though component or ambari does not hold the notion of HA for it like ZK servers)
> *Verification of the patch:*
> On resolution of this patch, Yarn refresh queue command will automatically appear for Active Resource Manager component action menu.
> After enabling ResourceManager HA, the command link for "Refresh Queue" will be enabled only on active RM
