Support bulk enqueue with differing class and options
Browse files Browse the repository at this point in the history 
Allow bulk enqueue of multiple different job classes and differing job
options in a single `.bulk_enqueue` block. Each job can now differ by
job class, queue, priority, run at and tags (in addition to args and
kwargs).
