Multiple Queue improvements: LevelDB Wait on empty, shutdown empty shadow level queue, reduce goroutines etc (#15693) 
* move shutdownfns, terminatefns and hammerfns out of separate goroutines

Coalesce the shutdownfns etc into a list of functions that get run at shutdown
rather then have them run at goroutines blocked on selects.

This may help reduce the background select/poll load in certain
configurations.

* The LevelDB queues can actually wait on empty instead of polling

Slight refactor to cause leveldb queues to wait on empty instead of polling.

* Shutdown the shadow level queue once it is empty

* Remove bytefifo additional goroutine for readToChan as it can just be run in run

* Remove additional removeWorkers goroutine for workers

* Simplify the AtShutdown and AtTerminate functions and add Channel Flusher

* Add shutdown flusher to CUQ

* move persistable channel shutdown stuff to Shutdown Fn

* Ensure that UPCQ has the correct config

* handle shutdown during the flushing

* reduce risk of race between zeroBoost and addWorkers

* prevent double shutdown

Exponential Backoff for ByteFIFO (#15724) 
This PR is another in the vein of queue improvements. It suggests an
exponential backoff for bytefifo queues to reduce the load from queue
polling. This will mostly be useful for redis queues.

Only use boost workers for leveldb shadow queues (#15696) 
* The leveldb shadow queue of a persistable channel queue should always start with 0
workers and just use boost to add additional workers if necessary.

* create a zero boost so that if there are no workers in a pool - boost to start the workers

* actually set timeout appropriately on boosted workers

Always set the merge base used to merge the commit (#15352) 
The issue is that the TestPatch will reset the PR MergeBase - and it is possible for TestPatch to update the MergeBase whilst a merge is ongoing. The ensuing merge will then complete but it doesn't re-set the MergeBase it used to merge the PR.

Fixes the intermittent error in git test.

Prevent timer leaks in Workerpool and others (#11333) 
There is a potential memory leak in `Workerpool` due to the intricacies of
`time.Timer` stopping.

Whenever a `time.Timer` is `Stop`ped its channel must be cleared using a
`select` if the result of the `Stop()` is `false`.

Unfortunately in `Workerpool` these were checked the wrong way round.

However, there were a few other places that were not being checked.
