With serviceUrlProvider we can store the pulsar service url in zookeeper or any other config service. And we can watch the service url change event then control the pulsar client, such as change pulsar client serviceUrl, force close client connection or re-connect with new service url. ### Modifications Add ServiceUrlProvider interface. Add forceCloseConnection method in PulsarClient.
