Re: [Hawkular-dev] integrating ansible and hawkular to start remote wildfly servers

Slight change - I found out there is a feature in feature-pack stuff that let you ship with direct file content that gets copied into the server. So I put the Ansible scripts in the feature pack. This is the correct way to do it. Now anyone building the server with the feature pack (integration tests, for example) will get the Ansible integration as well. So link [3] changes from my original email.
