[feature] add the ability to override the ConsumerConfiguration per Session/JMSContext

[eolivelli]

Modifications

• add JMSContext.createContext(int mode, Map<String, Object> customConfiguration)
• add Session.createSession(int mode, Map<String, Object> customConfiguration)

In order to override the consumerConfiguration the code looks like:

Map<String, Object> properties = ...;


Map<String, Object> overriddenProperties = new HashMap<>();
Map<String, Object> overriddenConsumerConfig = new HashMap<>();
overriddenProperties.put("consumerConfig", overriddenConsumerConfig);

try (PulsarConnectionFactory factory = new PulsarConnectionFactory(properties);
      PulsarJMSContext primaryContext = factory.createContext(JMSContext.CLIENT_ACKNOWLEDGE);
      JMSContext overrideConsumerConfiguration = primaryContext.createContext(primaryContext.getSessionMode(),
                  overriddenConsumerConfig) {
       

}

The same works with the JMS 1.x API (Session)

Modifications:

• move the Consumer configuration to a separate class
• add the necessary methods to the APIs
• add tests

Fixes #59 59
