Dmitriy Ukhlov 990d894eaf Move server related logic from dispatchers
Dispatcher should be responsible for routing message to the
callback method of endpoint object and returning result back to the
server only. But now it is also responsible for sending reply,
ack/reque messages etc.

Also this patch makes small improvements:
   1) Notification dispatcher now requeue message if endpoint raises exception
   2) unstable behaviour of test_mask_passwords test is fixed
