check_redis_publish_subscribe.pl

Nagios Plugin to check a Redis server is up and working via publish/subscribe API calls

Checks:

1. Subscribes to a unique channel
2. Publishes to that same unique channel with a randomly generated and timestamped token
3. Waits for the channel to feed the message through for a given number of secs
4. Checks the message received is the same as the one published
5. compares each operation's time taken against the warning/critical thresholds if given
