      Description

      We (cc Inigo/Botong Huang) observed that the FederationInterceptor in AMRMProxy (and consequently the AM) is blocked if the StateStore has outdated info about a SubCluster. This is because we handle AM register requests synchronously. This jira proposes to move to async similar to how we operate with allocate invocations.
