#11804) ### Motivation When a producer is getting error because of ProducerBusy (existing producer with the same name), it will trigger a producer close operation that will eventually lead to the existing producer getting removed from the topic map (even though that producer is still writing on the topic). The problem is the producer close is triggering a removal from the map: pulsar/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/AbstractTopic.java Line 683 in 43ded59 if (producers.remove(producer.getProducerName(), producer)) { Even though we check for producer equality, the Producer.equals() is only comparing the producer name, so the old instance gets removed from the map. Instead, the equality of producer needs to be based on the connection id (local & remote addresses and unique id), plus the producer id within that connection. * Producer getting producer busy is removing existing producer from list * Fixed test (cherry picked from commit 6aef83f)

### Motivation apache/pulsar#11804 added the custom implementations of `equals` and `hashCode` methods of `ServiceCnx`, which made KoP's spotbugs check fail with > Medium: io.streamnative.pulsar.handlers.kop.InternalServerCnx doesn't override org.apache.pulsar.broker.service.ServerCnx.equals(Object) [io.streamnative.pulsar.handlers.kop.InternalServerCnx] At InternalServerCnx.java:[line 1] EQ_DOESNT_OVERRIDE_EQUALS ### Modifications This PR adds the overrided `equals` and `hashCode` methods by calling base class' same name methods simply. On the other hand, since the new `equals` and `hashCode` methods are based on `ctx` field and they are called when removing `Producer` from `Topic`, this PR also updates the `ctx` field of `InternalServerCnx`.

Motivation
When a producer is getting error because of ProducerBusy (existing producer with the same name), it will trigger a producer close operation that will eventually lead to the existing producer getting removed from the topic map (even though that producer is still writing on the topic).
The problem is the producer close is triggering a removal from the map:
pulsar/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/AbstractTopic.java
Line 683 in 43ded59
Even though we check for producer equality, the
Producer.equals()
is only comparing the producer name, so the old instance gets removed from the map.Instead, the equality of producer needs to be based on the connection id (local & remote addresses and unique id), plus the producer id within that connection.
