Creates a global redis instance and exposes functions to use it.

Val.town runs in ohio so the best region to pick for the redis instance is probably us-east-1.
Calls are also traced via https://www.val.town/v/saolsen/tracing so if you use that library you will see timed spans for any redis calls.
For an example of how to use it see https://www.val.town/v/saolsen/try_redis
