ipcpd: normal: Handle enrollment replies

This adds a condition variable with a timeout to the CDAP request so
that we can respond correctly to the answer from the remote. It also
adds a timeout to the condition variable waiting on completion of
enrollment. Furthermore, for every CDAP callback a new thread is now
spawned, to avoid deadlocking in case a callback is stuck.
