[performance] massively improved ActivityPub delivery worker efficiency (#2812) * add delivery worker type that pulls from queue to httpclient package * finish up some code commenting, bodge a vendored activity library change, integrate the deliverypool changes into transportcontroller * hook up queue deletion logic * support deleting queued http requests by target ID * don't index APRequest by hostname in the queue * use gorun * use the original context's values when wrapping msg type as delivery{} * actually log in the AP delivery worker ... * add uncommitted changes * use errors.AsV2() * use errorsv2.AsV2() * finish adding some code comments, add bad host handling to delivery workers * slightly tweak deliveryworkerpool API, use advanced sender multiplier * remove PopCtx() method, let others instead rely on Wait() * shuffle things around to move delivery stuff into transport/ subpkg * remove dead code * formatting * validate request before queueing for delivery * finish adding code comments, fix up backoff code * finish adding more code comments * clamp minimum no. senders to 1 * add start/stop logging to delivery worker, some slight changes * remove double logging * use worker ptrs * expose the embedded log fields in httpclient.Request{} * ensure request context values are preserved when updating ctx * add delivery worker tests * fix linter issues * ensure delivery worker gets inited in testrig * fix tests to delivering messages to check worker delivery queue * update error type to use ptr instead of value receiver * fix test calling Workers{}.Start() instead of testrig.StartWorkers() * update docs for advanced-sender-multiplier * update to the latest activity library version * add comment about not using httptest.Server{}

[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
