Add Gitlab::Redis::Sessions Redis instance
This will involve a new class Gitlab::Redis::Sessions inheriting from https://gitlab.com/gitlab-org/gitlab/blob/f1b74329658238a0014af6dd714e1b588ad7fa15/lib/gitlab/redis/wrapper.rb. It is probably similar to the TraceChunks class, falling back to the SharedState.

This instance should not be used yet.
