Use async-rediscache package for our redis caches

I've migrated our redis caches over to the async-rediscache package that
we've recently released (https://git.pydis.com/async-rediscache). The
main functionality remains the same, although the package handles some
things, like getting the active session, differently internally.

The main changes you'll note for our bot are:

- We create a RedisSession instance and ensure that it connects before
  we even create a Bot instance in `__main__.py`.

- We are now actually using a connection pool instead of a single
  connection.

- Our Bot subclass now has a new required kwarg: `redis_session`.

- Bool values are now properly converted to and from typestrings.

In addition, I've made sure that our MockBot passes a MagicMock for the
new `redis_session` kwarg when creating a Bot instance for the spec_set.
