Add Redis configuration and connection

This adds configuring redis for all of Qs and also adds a utility
for building a redis connection. Qs will build a redis connection
when init which it will use to add jobs and publish events. Daemons
will also build redis connections for pulling jobs off of a queue.
Daemons will also use the global Qs redis configuration for
building their connection.

Add Redis configuration and connection
Add `DaemonData`

This adds a `DaemonData` class which handles "compiling" a daemons
configuration. This is done for speed and to provide a simple
object for passing around the daemon configuration. This provides
methods for easily looking up a queue and route, which will be
used to run a job handler. The daemon data also provides the redis
configuration which will be used to build a redis connection when
the daemon is run.
