[performance] update remaining worker pools to use queues (#2865)

* start replacing client + federator + media workers with new worker + queue types

* refactor federatingDB.Delete(), drop queued messages when deleting account / status

* move all queue purging to the processor workers

* undo toolchain updates

* code comments, ensure dereferencer worker pool gets started

* update gruf libraries in readme

* start the job scheduler separately to the worker pools

* reshuffle ordering or server.go + remove duplicate worker start / stop

* update go-list version

* fix vendoring

* move queue invalidation to before wipeing / deletion, to ensure queued work not dropped

* add logging to worker processing functions in testrig, don't start workers in unexpected places

* update go-structr to add (+then rely on) QueueCtx{} type

* ensure more worker pools get started properly in tests

* fix remaining broken tests relying on worker queue logic

* fix account test suite queue popping logic, ensure noop workers do not pull from queue

* move back accidentally shuffled account deletion order

* ensure error (non nil!!) gets passed in refactored federatingDB{}.Delete()

* silently drop deletes from accounts not permitted to

* don't warn log on forwarded deletes

* make if else clauses easier to parse

* use getFederatorMsg()

* improved code comment

* improved code comment re: requesting account delete checks

* remove boolean result from worker start / stop since false = already running or already stopped

* remove optional passed-in http.client

* remove worker starting from the admin CLI commands (we don't need to handle side-effects)

* update prune cli to start scheduler but not all of the workers

* fix rebase issues

* remove redundant return statements

* i'm sorry sir linter
