[dependabot]

Bumps rq from 2.7.0 to 2.9.0.

Release notes

Sourced from rq's releases.

v2.9

• Added json and pickle shorthand aliases for serializers. These can now be used when creating queues/workers and with the --serializer CLI option. Thanks @​selwin!
• Fixed a bug where SpawnWorker does not use user supplied serializer. Thanks @​selwin!
• Queue.parse_args() now returns a EnqueueArgs named tuple. Thanks @​libmilos-so!
• Fixed a race condition that could cause worker keys in Redis to get out of sync when Redis is under load. Thanks @​terencehonles!
• Enqueueing deferred jobs now removes them from DeferredJobRegistry. Thanks @​selwin!
• SpawnWorker now uses repr() when reconstructing worker, job and queue identifiers in child processes. Thanks @​selwin!
• Minor typing and cleanup improvements. Thanks @​selwin and @​rextea!

v2.8

• Added support for unique jobs. Passing unique=True with job_id prevents duplicate jobs from being enqueued or scheduled. Thanks @​selwin!
• Result now stores execution metadata (execution_id, execution_started_at and execution_ended_at). Thanks @​selwin!
• Retry now supports enqueue_at_front=True, allowing retried jobs to be requeued at the front of the queue. Thanks @​crazillagodzilla!
• Custom job_id values may only contain letters, numbers, underscores and dashes. Thanks @​selwin!
• When a job is stopped, its dependencies are no longer enqueued. Thanks @​selwin!
• DeferredJobRegistry is now scored by job creation time. Thanks @​selwin!
• Workers now print a warning instead of raising an exception when CLIENT LIST is not supported. Thanks @​selwin and @​djmaze!
