> When losing the leadership the {{JobManagerLeaderListener}} closes the current {{rpcConnection}} but does not clear the field. This can lead to a failure of {{JobManagerLeaderListener#reconnect}} if this method is called after the {{JobMaster}} has lost its leadership.
> I propose to clear the field so that {{RegisteredRpcConnection#tryReconnect}} won't be called on a closed rpc connection.
