* added Dependency class with allow_failures
* Requested changes
* Check type before setting `job.dependency_allow_fail` within `Job.create`
* Set `job.dependency_allow_fail` within `Job.create`
* Added test to ensure persistence of `dependency_allow_fail`
* Removed typing and allow mixed list of ints and Job objects
* Convert dependency_allow_fail boolean to integer during serialization to avoid redis DataError
* Updated `test_multiple_dependencies_are_accepted_and_persisted` test to include `Dependency` cases
* Adding placeholder test to test actual behavior of new `Dependency` usage in `depends_on`
* Updated `test_job_dependency` to include cases using `Dependency`
* Added dependency_allow_fail logic to `Job.restore`
* Renamed `dependency_allow_fail` to a simpler `allow_failure`
* Update docs to add section about the new `Dependency` class and use-case
* Updated `Job.dependencies_are_met` logic to take `FAILED` and `STOPPED` jobs into account when `allow_failure=True`
* Updated `test_job_dependency` test. Still failing with `Dependency` case.
* Fix `allow_failure` type coercion in `Job.restore`
* Re-arrange tests, so default `Dependency.allow_failure` is before explicit `allow_failure=True`
* Fixed Dependency, so it works correctly when allow_failure=True
* Attempt to execute pipeline prior to queueing a failed job's dependents. test_create_and_cancel_job_enqueue_dependents_in_registry test now passes.
* Added `Depedency` test utilizing multiple dependencies
* Removed irrelevant on_success and on_failure keyword arguments in example
* Replaced use of long_running_job
* Add test to verify `Dependency.jobs` contraints
* Suppress connection error in handle_job_failure
* test_dependencies have passed
* All tests pass if enqueue_dependents called without pipeline.watch()
* All tests now pass
* Removed print statements
* Cleanup Dependency implementation
* Renamed job.allow_failure to job.allow_dependency_failures
