There appears to be an intermittent NPE in queue tests relating to the deferred
shutdown/terminate functions.
This PR more formally asserts that shutdown and termination occurs before starting
and finishing the tests but leaves the defer in place to ensure that if there is an
issue shutdown/termination will occur.

Continues on from #19202.
Following the addition of pprof labels we can now more easily understand the relationship between a goroutine and the requests that spawn them.
This PR takes advantage of the labels and adds a few others, then provides a mechanism for the monitoring page to query the pprof goroutine profile.
The binary profile that results from this profile is immediately piped in to the google library for parsing this and then stack traces are formed for the goroutines.
If the goroutine is within a context or has been created from a goroutine within a process context it will acquire the process description labels for that process.
The goroutines are mapped with there associate pids and any that do not have an associated pid are placed in a group at the bottom as unbound.
In this way we should be able to more easily examine goroutines that have been stuck.
A manager command `gitea manager processes` is also provided that can export the processes (with or without stacktraces) to the command line.

* Attempt to prevent the deadlock in the QueueDiskChannel Test again
This time we're going to adjust the pause tests to only test the right
flag.
* Only switch off pushback once we know that we are not pushing anything else
* Ensure full redirection occurs
* More nicely handle a closed datachan
* And handle similar problems in queue_channel_test

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
