* job: add get_meta() function
The newly introduced function returns meta data stored for the job. This
is required since job.meta stays an empty dict until the job is
finished or failed.
With the new function it's possible to store arbiatraty states/stages of
the job and allow the user to track progress. A long running job may
return custom stages like `downloading_data`, `unpacking_data`,
`processing_data`, etc.
This may allow better interfaces since users can track progress.

This is required to get the test to pass under other serializers / other
python versions.

We now represent the entire list, instead of just the first element.

* Initial implementation of Retry class

* Added docs for job retries
The variable contains the server version and allows to determine
available features. This is relevant for API changes like HSET mappings
in version 4.0.0 or LPOS in version 6.0.6.
To keep the number of connection.info() calls low, the information is
*cached* once determined, as a server version unlikely changes while
keeping the connection up.

* Rename `dependent_jobs` to `jobs_to_enqueue` in queue.py
* Rename `dependencies_job_ids` to `dependency_ids`.
* Remove `as_text` (no more python2 support). Use `bytes.decode`
1) Check if `created_at` when checking if dependencies are met.
If `created_at` is `None` then the job has been deleted. This is sort of hack - we just need one of the fields on the job's hash that is ALWAYS populated. You can persist a job to redis without setting status...
2) Job#fetch_dependencies no longer raises NoSuchJob.
If one of a job's dependencies has been deleted from Redis, it is not returned from `fetch_dependencies` and no exception is raised.
When a job with dependents is _successful_ it's dependents are enqueued. Only if the FINISHing job's `result_ttl` is non-zero is the change in status persisted in Redis - that is, when each dependent job is enqueued, the _FINISHing_ job (,triggering the enqueueing,) has an _outdated_ status in redis. This avoids redundant call because if `result_ttl=0` then the job is deleted then deleted in `Job#cleanup`.
In order to enqueue the dependents, we therefore _exclude_ the FINISHing job from the check if each dependents' dependencies have been met.
* Add job status setting in enqueue_at (and in enqueue_in) methods
Update tests for this change
Closes: #1179
* Add status param to create_job func, rework enqueue_at status setting

* Added ScheduledJobRegistry.get_scheduled_time(job)
* WIP on scheduler's threading mechanism
* Fixed test errors
* Changed scheduler.acquire_locks() to instance method
* Added scheduler.prepare_registries()
* Somewhat working implementation of RQ scheduler
* Only call stop_scheduler if there's a scheduler present
* Use OSError rather than ProcessLookupError for PyPy compatibility
* Added `auto_start` argument to scheduler.acquire_locks()
* Make RQScheduler play better with timezone
* Fixed test error
* Added --with-scheduler flag to rq worker CLI
* Fix tests on Python 2.x

* Multi Dependency Support - Registration & Enqueue Call
Internal API changes to support multiple dependencies.
* Store all of a job's _dependencies_ in a redis set. Delete that set when a job is deleted.
* Add Job#fetch_dependencies method - which return all jobs a job is dependent upon and optionally _WATCHES_ all dependency ids.
* Use Job#fetch_dependencies in Queue#call_enqueue. `fetch_dependencies` now sets WATCH and raises InvalidJobDependency, rather than call_enqueue.
`Queue` and `Job` public APIs still expect single ids of jobs for `depends_on` but internally register them in a way that could support multiple jobs being passed as dependencies.
Next up: need to update Queue#enqueue_dependents
* Use existing fetch_many method to get dependencies.
Modify fetch_dependencies to use fetch_many.
* Remove default value for fetch_many's connection parameter
* PR review housekeeping
* Remove a duplicate test
* Oneline something
* Fix missing colon in dependencies key
* Delete job key, dependents and dependencies at once
* More Fixes From Code Review
Updates to Job, Queue and associated tests.
* When Checking dependencies Avoid, trip to Redis
* When checking the status of a job, we have a 'clean' status of all dependencies(returned from Job#fetch_dependencies) and the job keys are WATCHed, so there's no reason to go back to Redis to get the status _again_.
* Looks as though, the `_status` set in `Job#restore` was bytes while it was converted to text(`as_text`) in `Job#get_status` - for consistency(and tests) converting to text in `restore` as well.
* In `Queue#enqueue_call`, moved WATCH of dependencies_key to before fetching dependencies. This doesn't really matter but seems more _correct_ - one can imagine some rogue API adding a dependency after they've been fetched but before they've been WATCHEed.
* Update Job#get_status to get _local_ status
* If refresh=False is passed, don't get status from Redis; return the value of _status. This is to avoid a trip to Redis if the caller can guarantee that the value of `_status` is _clean_.
* More Fixups
* Expire dependency keys in Job#cleanup
* Consistency in Job#fetch_dependencies
* Convert `_dependency_id` to `_dependency_ids`
Change `Job`s tracking from a single id of it's dependencies from a single _id_ to a list of _id_s. This change should be private to `Job` - especially leaving `Job#to_dict` and `Job#restore`s treatment of a single 'dependency_id' intact.
This change modifies existing tests.
* Remove reliance upon dependency property in tests
... use dependency.id not `_dependency_id`
* Re-add assertions for Falsey Values
* Add _dependency_id property
