Documentation on how to configure Resource Adapter to process messsage seqentially from the same JMSXGroupID when dispatching to MDBs

There is an use case where messages from the same JMSXGroupID needs to be processed sequentially when dispatching to a pool of MDBs.

ActiveMQ does not provide the feature out of box but solution is to configure prefetch=1. However, we also need to configure usePrefetchExtension=false to help prefetch=1 due to this JIRA: https://issues.apache.org/jira/browse/AMQ-2651. When set, when the broker gets a delivery ack, indicating that the consumer has received the message but the application has not acked the message, the broker can dispatch another message. This means the prefetch=1 is really prefetch=X where X is the number of concurrent consumers. When the prefetch extension is disabled, prefetch=1 is really dispatch a single message till it is acked.

For more details, please take a look at this Fuse MQ Enterprise JIRA: ENTMQ-261
