Sanity tests related to number of packets, packet size & packet priority

Browse Source 
Summary:
related to T12015
- add tests related to sending/receiving really big packets
- add tests related to receiving multiple packets at once
- send_big_publish fails in the testing environment, but it works fine in real life
