> Handle client failover during 2 step client API's like app submission

> Issue Type: Sub-task

> Original Estimate: 48h
> Remaining Estimate: 48h
>
> App submission involves
> 1) creating appId
> 2) using that appId to submit an ApplicationSubmissionContext to the user.
> The client may have obtained an appId from an RM, the RM may have failed
> over, and the client may submit the app to the new RM.
> Since the new RM has a different notion of cluster timestamp (used to create
> app id) the new RM may reject the app submission resulting in unexpected
> failure on the client side.
> The same may happen for other 2 step client API operations.
