Merge 'Adding JMX Metric support'
From Amnon: "This series adopt the yammer Metric library to use with out API. The library it self is taken as is by adding it to the Maven dependency. The required adaptation is that information will not be added in push to the library Metric, instead, when required, the specific Metric would use the APIClient to fetch information from the system using the API. This approach would mean that there will be little adaptation when code would be passed from origin." Signed-off-by: Pekka Enberg <penberg@cloudius-systems.com> Conflicts: pom.xml
