* Define redis key prefix as class variable
Some prefixes were hardcoded in several places. This made it hard to
use custom prefixes via subclasses.
Resolves#920
* fixup! Define redis key prefix as class variable
* Initial take on delete_dependents
* Add tests including corner cases
* No need to canel dependents since they are not in a queue yet anyway
* The dependents keys can be deleted in all cases
* Update tests to included saved jobs in the deletion tests
* Correctly use pipeline in cancel method
* Unused connection
* Include dependents into dict format of job
* Add TODO
* Address comments from selwin
* Delete dependents key in redis if delete_dependents is called on its own
* Address recent comments from selwin
* Small change to trigger travis
* Remove TODO referring to canceled job state
* Remove dependent_ids from to_dict

After using `@job` decorator for a function that takes a long string, in RQ worker I got printed all the args/kwargs via `job.get_call_string()`.
To get this overridden, I added `description` argument to the decorator.
I decided not to put this in `delay` method because it's may be currently be used by end user.
* job.exc_info is now compressed.
* job.data is now stored in compressed format.
* Added worker_registration.unregister.
* Added worker_registration.get_keys().
* Modified Worker.all(), Worker.all_keys() and Worker.count() to accept "connection" and "queue" arguments.
* Fixed an issue where `birth` not present in Redis
Fixed an issue where worker.refresh() may fail if `birth` is not present in Redis
* added test coverage
* First stab at implementing worker statistics.
* Moved worker data restoration logic to worker.refresh().
* Failed and successfull job counts are now properly incremented.
* Worker now keeps track of total_working_time
* Ensure job.ended_at is set in the case of unhandled job failure.
* handle_job_failure shouldn't crash if job.started_at is not present.
