Manage communication channels from Gazelle Test Management for a particular test run

To ease the communication between the participants (SUT operators, monitors) involved in a particular test run, when a communication tool is made available by the management team, Gazelle Test Management shall be able to manage channels, and in particular:

• Create a private channel when a "peer to peer" test run is created (including with the "scheduled" status);
• Allow test partners to join the channel
• Add the monitor to the channel when he claims the test run;
• Remove the monitor from the channel when he unclaims the test run;
• Archive the channel when the status of the test run is set to a final status: Verified, Failed, Aborted.
• Unarchive the channel when the test run status is changed back to running.

The permanent link to the channel shall appear in the test run metadata pannel until it is archived.

As soon as the test session is set as "closed", all the test run channels shall be deleted.
