[feat][broker]PIP-180: ShadowTopic - Part I - Refactor replicator for ShadowReplicator

[Jason918]

Motivation

ShadowReplicator is part of PIP-180 (#16153).
ShadowReplicator and GeoReplicator(which implemented by PersistentReplicator) share most of the logics.
This PR refactor replicators so that shadow replicator can extends from PersistentReplicator in the next parts of PIP-180.
And moves the geo-replication related logics to GeoPersistentReplicator.

Modifications

• Add remoteTopicName in AbstractReplicator, for GeoReplicator : remoteTopic == localTopic, for ShadowReplicator: localCluster == remoteCluster.
• Add AbstractReplicator#replicatorId to help simplify logging info.
• Add GeoPersistentReplicator
• A lot of log replacement: log.info("[{}][{} -> {}],...",topicName, localCluster, remoteCluster,...) to log.info("[{}],...",replicatorId,...)
