* Move group into a separate helper module for reuse
* Add shutdownCh to worker
The shutdown channel is used to signal that worker has stopped.
* Make server shutdown block on workers' shutdownCh
* Fix waiting for eval broker state change blocking indefinitely
There was a race condition in the GenericNotifier between the
Run and WaitForChange functions, where WaitForChange blocks
trying to write to a full unsubscribeCh, but the Run function never
reads from the unsubscribeCh as it has already stopped.
This commit fixes it by unblocking if the notifier has been stopped.
* Bound the amount of time server shutdown waits on worker completion
* Fix lostcancel linter error
* Fix worker test using unexpected worker constructor
* Add changelog
