ansible fact caching redis password different port

00_README.md

Everything I've read is that redis fact caching in ansible doesn't support db/password/ports, but that is untrue. It's undocumented and it will most likely change in the future but here is how it works. it takes the fact_caching_connection and split's it on the colon and passes it as *args to redis.StrictRedis. Db is typically 0 if you weren't sure. If you aren't sure if the ansible version you are using supports this, just check the plugins/redis.py for how it passes the connection string to StrictRedis. Works with 2.2.0.0 at least.
