check replicator periodically to avoid issue due to zk missing watch
rdhabalia opened a new pull request #6674: [pulsar-broker] check replicator periodically to avoid issue due to zk missing watch
URL: https://github.com/apache/pulsar/pull/6674
### Motivation
We have a regular issue when user changes replication-cluster list, many times broker misses the zk watch and broker fails to update replicator which causes either data loss or message backlog based on zk-watch missing at source or destination replication broker.
### Modification
- Broker expires replication policies at every X seconds
- Starts a background task which checks polices (fetches new policies if it's already expired) and starts/stops replicator if needed.
### Result
Broker can start/stop replicators based on updated policies even if broker misses zk watch.
