Adds in call to new rate limit method in the redis client

- both V1 and V2 APIs
- Rate limiting wrapped into a new method - check_rate_limiting
	- delegates to the previous daily limit and the new though put limit
- Rate limiting done on key type. Each key has it's own limit (number of requests) and interval (time period of requests)
- Configured in the config. Not done on a per-env basis though could be in the future.
