[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{}
