Scheduler: adds optional support for redis and specifying redis clientfeature/scheduler_redis_cluster_support

- allow optional support for running the scheduler without a redis
  backend for persistent schedule storage. The default is to exit on
  startup error. The user can set `redis_startup_error_hard_kill` to
  false if they really want to run the scheduler with no backend db.
- allow users the ability to specify a redis client class. this will let
  them use redis-cluster if they wish. They can install the appropriate
  module and define `redis_client_class` (and if necessary class keyword
  arguments via `redis_client_class_kwargs`).
