Add Redis lock periodic renewal

Although `RenewableLockRegistry` provides a renew interface, it is inconvenient for users.
Developers hope to have a lock that can be automatically renewed.
On the one hand, it can avoid subsequent failures caused by locks that will not expire when abnormal exits,
and on the other hand, it can avoid unlock failures caused by lock expired.

* Add `RenewableLockRegistry.setRenewalTaskScheduler()` and when it is set, schedule a `renew()` script periodically
when lock is acquired  from Redis with `1/3` of `expireAfter`
* Test and document the feature

 The pub-sub is preferred mode - less network chatter between client Redis server, and more performant - the lock is acquired immediately when subscription is notified about unlocking in the other process.
 However, the Redis does not support pub-sub in the Master/Replica connections (for example in AWS ElastiCache environment), therefore a busy-spin mode is chosen as a default to make the registry working in any environment.
