   ## What is the purpose of the change
   
   
   The problem is that the Dispatcher actor is being started before it gains leadership. When using the
   standalone high availability services, then we don't wait until the Dispatcher has confirmed its
   leader session id. We only wait until the actor has become available. Due to that it can happen that
   we try to send a RPC message to the Dispatcher before it has actually set its leader session id.
   
   This commit adds a helper function which waits until the Dispatcher has become available and has set
   its leader session id. The proper way to handle this situation would be to move the leader ship grant
   and revokal out of the Dispatcher into a DispatcherRunner which creates a Dispatcher actor once it
   gained leadership.
