Graceful Queues: Issue Indexing and Tasks (#9363)
* Queue: Add generic graceful queues with settings * Queue & Setting: Add worker pool implementation * Queue: Add worker settings * Queue: Make resizing worker pools * Queue: Add name variable to queues * Queue: Add monitoring * Queue: Improve logging * Issues: Gracefulise the issues indexer Remove the old now unused specific queues * Task: Move to generic queue and gracefulise * Issues: Standardise the issues indexer queue settings * Fix test * Queue: Allow Redis to connect to unix * Prevent deadlock during early shutdown of issue indexer * Add MaxWorker settings to queues * Merge branch 'master' into graceful-queues * Update modules/indexer/issues/indexer.go Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * Update modules/indexer/issues/indexer.go Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * Update modules/queue/queue_channel.go Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * Update modules/queue/queue_disk.go * Update modules/queue/queue_disk_channel.go Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * Rename queue.Description to queue.ManagedQueue as per @guillep2k * Cancel pool workers when removed * Remove dependency on queue from setting * Update modules/queue/queue_redis.go Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * As per @guillep2k add mutex locks on shutdown/terminate * move unlocking out of setInternal * Add warning if number of workers < 0 * Small changes as per @guillep2k * No redis host specified not found * Clean up documentation for queues * Update docs/content/doc/advanced/config-cheat-sheet.en-us.md * Update modules/indexer/issues/indexer_test.go * Ensure that persistable channel queue is added to manager * Rename QUEUE_NAME REDIS_QUEUE_NAME * Revert "Rename QUEUE_NAME REDIS_QUEUE_NAME" This reverts commit 1f83b4fc9b9dabda186257b38c265fe7012f90df.
