[M] Change in osmo-ttcn3-hacks[master]: MGW_Tests: Add test for "confecho" connection.

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/33720 ) Change subject: MGW_Tests: Add test for "confecho" connection. ...................................................................... MGW_Tests: Add test for "confecho" connection. The test uses two connections: "confecho" and "sendonly". It is expected that "confecho" connection receives as many RTP packets as it sends, because it echoes back its packets. It is also expected that "sendonly" connection receives the same amount of RTP packets.
