/** <module> Configure Redis

SWISH may be configured to use the Redis key-value store for the various
databases. This allows multiple SWISH instances to act as a cluster.

Typically the configuration needs to be edited in two places:

  - redis_server/3 must be called to address the Redis server
  - redis_consumer may be set to identify this instance.  The
    default is derived from the host name and port to which
    this SWISH instance listens.  Clusters are advised to
    assign a stable name to each cluster member.
