* 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
