Audit Sentinel Config 
This tool is intended to run on a Sentinel node. It will troll through the local sentinel config file looking for known errors, and issue a report on what it finds.
Generally you want to run it with the '-report=all' flag.
Important bits to know
This tool does a tad more than simply reading the config file and checking it. It also connects to the Redis instances to do some additional checking. It also will connect to known sentinels to validate the other sentinels are available.
As such it needs to be run on the Sentinel and will expect to connect to Redis masters, slaves, and other sentinels. Normally this shouldn't be a problem as you should be running it on the Sentinel which also requires this connectivity.
TODO List
- add example "bad" sentinel config for testing
- add example "good" sentinel config for testing
