Publisher Worker Queue: Update Resolution

[AndyTWF]

Implement the following AAT Android worker:

• UpdateResolution
• UpdateResolutionSuccess

UpdateResolution is responsible for updating the Publishers presence data when a new resolution is resolved (in publisher.resolveResolution).

If the resolution is not currently queued for update, it is added to a list of publisher resolutions to be updated. If the resolution is not the latest resolution to be added (for example, in practice, another has come along and the presence update failed), then it is removed and the operation terminates.

Otherwise, we wait for the ably channel to attach and update presence data to include the latest resolution. If this results in a fatal error or is successful, UpdateResolutionSuccess work is posted. Otherwise, the resolution update is retried.

The UpdateResolutionSuccess worker removes the resolution from the update queue.

This work depends on:

• Ably SDK Wrapper: Implement waiting for Ably channel to attach #562

This work is implemented almost identically to the workers in the following task, so may benefit from taking what's already been done:

• Subscriber Worker Queue: Change Resolution #584
