> Currently BroadcastAMRMProxyPolicy assumes that we only span the application to the sub-clusters
instructed by itself via _splitResourceRequests_. However, with AMRMProxy HA, second attempts
of the application might come up with multiple sub-clusters initially without consulting the
AMRMProxyPolicy at all. This leads to exceptions in _notifyOfResponse._ It should simply allow
the new/unknown sub-cluster heartbeat responses.
