This PR fixes an issue with duplicate metrics registration and sending to a closed channel on config changes. By wrapping the mailboxes we can prevent them from explicitly being closed. This can happen in the middle of a scrape where the metrics are still being written to the old endpoint.
This also starts laying the ground work for draining the loops before stopping them to preserve metrics.
