Subscriber Worker Queue: Change Resolution

[AndyTWF]

Implement the following workers for the Subscriber:

• ChangeResolution
• ChangeResolutionSuccess

ChangeResolution is enqueued from the subscriber when the libraries consumer wishes to set a resolution preference for the subscriber. The logic of changing resolution is essentially identical to that of: #566, except the fact that ChangeResolutionSuccess work is posted upon completion.

@AndyTWF I think that ChangeResolutionSuccess only exists in the publisher SDK – in the subscriber SDK it directly calls the callback function. Actually, I can't see ChangeResolutionSuccess at all – where does that come from?
