Motivation
Pulsar Proxy will create a new Pulsar Client instance for every proxied connection.
Currently 2 threads will be created for every Pulsar Client instance for the internal/IO and external/listener executors. This causes a lot of overhead and inefficiency in the Pulsar Proxy.
It turns out that the PulsarClientImpl instance is unnecessary in Pulsar Proxy. The Proxy code doesn't need the instance at all and therefore it can be removed.
While working on the changes, it was noticed that the ConnectionPool cleanup code is wrong. It is closing the EventLoopGroup provided to the ConnectionPool although ConnectionPool doesn't create this resource. In addition, closing didn't close existing connections.
