Add redis gem stuff
Add redid configurations
Convert using ruby array's into redid backend
Add json serialization for redis
Add ranking for Redis sorted set
Support "perform_at" for expected_next_run
Remove configuration loading from scheduler
Fix method names in Agent::Probe
Just call the runner directly from the Agent tree

This should be simplified later.  Probably pass in whatever actors we need and crash the current actor if any linked actors go down.
Then the runner will start as necessary with a whole new set of actors.
Remove testing the get method which has been delegated to redis.
Test work ranking
