Tested getting the HTTP "Accept" header with @HeaderParam("Accept")
String acceptHeader so we can implement ReST API versioning.

: obotest - RabbitMQ message consumption on GlassFish 

Task-Url:
Changed a few ReST monitoring details unrelated to ansynchronous calls.
Direct calls to the message handler, asychronous and synchronous seem to
work OK. I need to do a little more testing before I finish this
feature.
Some minor adjustments that I want to commit before I rename a number of
objects.
Minor edits before I rename many objects to change "unacknowledged CDI
events" to "unserviced asynchronous calls".
Merge branch 'feature/async-call' into develop
Almost finished renaming, but I want to commit now for a savepoint.
Finished renaming objects and comments.
