Updating changelog
Fixed regression for previous work for SHDP-141

On some cases parameters passed via command line were
incorrectly processed.
Adding better support for long running containers SHDP-154

Add similar concepts from appmaster where we have state listener
for container and runner is able to check if container is requesting
wait for complete state.
Work for SHDP-152 and SHDP-153.

Adding better handling for running appmaster services. We can also
now register tracking url if that kind of service is known to
appmaster. Also some housekeeping and more logging.
Work for yarn test system SHDP-140

Update spring core from 3.0.7 to 3.1.3, needed by deps
to spring-test. Add minicluster concepts from hadoop
which integrates into general testing concepts from
spring-test. This work should allow users to unit test
custom yarn applications without need to have
a real cluster up and running.
