…ers per connection ### Motivation This is a catch up for apache/pulsar#21144 When a producer or consumer reconnects, a random number will be generated as the key suffix in `ConnectionPool` to create or get the `ClientConnection` object from the pool. https://github.com/apache/pulsar-client-cpp/blob/81cc562f7b366fad97e1b80c07ef9334a808390d/lib/ConnectionPool.cc#L75 If a new connection is created with the same producer or consumer name to the broker, the broker will respond with a `ProducerBusy` or `ConsumerBusy` error so that the reconnection will never succeed. ### Modifications - Add an overload of `ConnectionPool::getConnectionAsync` that accepts an integer parameter as the key suffix. If it's not specified, generate the random number as the suffix. In this method, choose the executor by `key suffix % size`. - Generate the random number and save it when creating the `HandlerBase` object. When connecting the owner broker of its topic, pass that index so that the reconnection will always reuse the same `ClientConnection` object. ### Verifying this change `ProducerTest.testReconnectMultiConnectionsPerBroker` is added to protected the change.
