There are few problems with this way of closing the connections.
channelInactive() is supposed to be called by Netty when the connection gets closed. With the current approache the original TCP connection will stay open and the broker will still have registered the producer/consumer as connected.
The right approach here should be to close all the connections in the ConnectionPool. That will be triggering the reconnections for all producers/consumers.

Support build Pulsar client with serviceUrlProvider method.
Motivation
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.
