> Concurrent registerAM thread in Federation Interceptor

>
> The timeout between AM and AMRMProxy is shorter than the timeout + failOver
> between FederationInterceptor (AMRMProxy) and RM. When the first register
> thread in FI is blocked because of an RM failover, AM can timeout and resend
> register call, leading to two outstanding register call inside FI.
> Eventually when RM comes back up, one thread succeeds register and the other
> thread got an application already registered exception. FI should swallow the
> exception and return success back to AM in both threads.
