watchRTC as a feature for Jitsi meet

[subhamcyara]

Following PR contains changes required to add watchRTC as a module within lib jitsi meet

This involves adding

• watchRTC SDK package (npm i @testrtc/watchrtc-sdk).
• watchRTC SDK is initialized within Statistics.init to proxy WebRTC functions such as GUM and RTCPeerConnection.
• watchRTC SDK then starts collecting required stats when the conference begins. Here we check if the user has not configured room name or user/peer name, if not, then use relevant data available from Jitsi.
• watchRTC SDK does not require to function for react native.
• checks implemented to run watchRTC SDK when
  -- watchRTC is enabled
  -- rtcstats must be disabled
  -- analytics should be enabled
  -- third party requests are not disabled

Hi, thanks for your contribution!
If you haven't already done so, could you please make sure you sign our CLA (https://jitsi.org/icla for individuals and https://jitsi.org/ccla for corporations)? We would unfortunately be unable to merge your patch unless we have that piece :(.

This is no longer the case. We used to store window.PeerConnection but we no longer do. Or did we miss a spot?

[subhamcyara]

I am not sure I understand. Is this about the verbose comment written and behaviour of the lib jitsi meet written within the comment ?!

[saghul]

It's about the comment.

Please use the exact version, aka, leave ^ out.

Please see the test failure, we are going to need to bump the library size.

[subhamcyara]

@saghul , I have tried to address all review points. Please let me know your feedback.
Thanks

[saghul]

The test failures seem legit. I think we should gate starting of watchRTC if it's not enabled or no room name was provided.

[subhamcyara]

I believe the failure should resolve now. For context, there are checks to see if watchRTC is enabled or not. The idea is to use the roomName and/or peerName from the watchRTC config and if not supplied, we can use what jitsi provides. If we get nothing from jitsi too, watchRTC SDK would handle it.

LGTM. @andrei-gavrilescu can you PTAL too?

[andrei-gavrilescu]

Looks good 👍

[saghul]

@subhamcyara Can you please rebase? Looks like there is some small conflict. Once solved it's good to merge.

Hi, thanks for the review here. I believe we might also need to take a look at jitsi/jitsi-meet#13527 for changes related to JM.

[saghul]

Jenkins please test this please.
