Refactored how reTOracle caches SQL responses with redis. SQL queries are now executed on-demand and on a per-query basis. New approach also now leverages redis.expire to set a 'time to live' for each cached value. Also did a lot of clean up and made get_redis_query() easier to use for basically all SQL queries moving forward.
Removed a random file that shouldn't be in the repro.
Fixed up some logging in get_redis_query.
Updated ticker_fetch so it'll use redis to query and cache results.
Updated get_latest_geo_tweet() to use redis for querying sql and caching results.
