Remove duplicate metrics in QueueManager

Browse Source 
Right now any new metrics added for remote write need to be added to
both the QueueManager struct, and the queueManagerMetrics struct.
Instead, use the queueManagerMetrics struct directly from QueueManager.

The newQueueManagerMetrics constructor will now create the metrics for a
specific queue with name and endpoint pre-populated, and a new copy of
the struct will be created specifically for each queue.

This also fixes a bug where prometheus_remote_storage_sent_bytes_total
is not being unregistered after a queue is changed.
