>    Affects Versions: 1.7.0
>            Reporter: Antonenko Alexander

> After resolution for, 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
