Allow for testing TURN credentials
Issue generated from Tuleap's migration script. Originally submitted by: Alexandre Viau (aviau)
I would like for clients to have a "Test connection" button next to the TURN credentials settings. It would allow users to check if they have configured their server properly and test authentication.
If a call fails because of bad TURN credentials, there is no clear error. Allowing users to test credentials will allow them to debug in a much more efficient manner.
