Currently, the only lockManager implementation in iceberg-core is InMemoryLockManager. This PR extends two LockManager implementations, one based on the Redis, and another based on the Rest-API. In general, most users use redisLockManager is sufficient to cope with most of the scenarios, for redis can not meet the user's requirements, we can let the user to provide a RestApi service to achieve this function. I believe that, for a long time, these two lock-manager's will satisfy most of the customer's needs.
