* feat(load-test): Senders unmute themselves if muted by policy.
* feat(load-test): Adds option to skip creating local audio track.
We currently create local audio track even when starting audio muted. Adding the option to control that can load test that for clients or signalling.
* fix(load-test): Always create local audio track.
When audio mutes will mute the track. Also fixes previous change where we do not add any of the tracks to the room.
* squash: Fix lint errors.
