This commit avoids a script duplication: the integration test runs the
sample instead of a copy of it in the repro directory.

Also switched the sample from ActiveMQ to HornetQ as #323 revealed
some locking on CI. Hopefully that should fix it as HornetQ is non
persistent and can be embedded several times in the same VM.

This commit binds RepositoryRestConfiguration to the spring.data.rest
prefix so that any of its property can be customized through the
environment.

If a RepositoryRestMvcConfiguration is defined in the context, those
customization do not apply, as it was the case before.

This commit deprecates the proprietary EnableJmsMessaging annotation in
favour of the standard @EnableJms introduced as of Spring 4.1. This
commit also updates the sample and adds an integration test as the
feature was actually broken.

Tomcat in particular sets an environment variable in it's shell scripts
that people commonly use to start the container. So if people deploy a war
file to a stock Tomcat server they can't override the logging config, even
with the default location. With this change at least that should work
(for logback and log4j anyway). Tested with logback.

Users could be surpised if they register a Filter with an @Order and it
