This PR is blocked for now I think, It's passing the tests locally. However in Jenkins :

stack_commons::newrelic on Centos 6.5 mysql with java doesn't include java recipe
     Failure/Error: end.converge('stack_commons::mysql_base', described_recipe)
     Chef::Exceptions::ResourceNotFound:
       resource ruby_block[Install plugin: newrelic_mysql_plugin] is configured to notify resource service[elasticsearch] with action restart, but service[elasticsearch] cannot be found in the resource collection. ruby_block[Install plugin: newrelic_mysql_plugin] is defined in /tmp/d20141031-29909-vijdor/cookbooks/elasticsearch/libraries/install_plugin.rb:35:in `install_plugin'

I think it's due to a definition called install_plugin in newrelic_plugins_chef https://github.com/newrelic-platform/newrelic_plugins_chef/blob/ba9ddd843560894494d134f67596a84ce5c4a172/definitions/install_plugin.rb, and one in elasticsearch https://github.com/elasticsearch/cookbook-elasticsearch/blob/master/libraries/install_plugin.rb#L35. so when newrelic_plugins_chef recipe is calling its definition to install a plugin, it actually triggers the elasticsearch plugin install.

I need to investigate more :-(

It's passing now with my fork : newrelic/newrelic_plugins_chef#29

I'm not sure it will be accepted upstream, so I'm trying to update our old rackspace_fork rackspace-cookbooks/newrelic_plugins_chef#1

I think it's okay to merge that PR on stack_commons It's long, but it's more tests than code :D
