Redis lock

[illenko]

Problem:

Now we have go-redis and for implementing distributed lock (common case for Redis usage) users have to write custom implementations of Locks.

Proposal:

To simplify the locks aquiring / releasing process would be better to have redislock out of the box.

In the code usage may look like:

lock, err := ctx.Redis().Locker().Obtain(ctx, "my-key", 100*time.Millisecond, nil)
