Move role and env definitions from server to chef-repo

Moved role definitions from the server to chef-repo so we can track
them in version control.  Added dev environment for development and an
attribute to barbican-db to be able to spin it up on public cloud.
Merge upstream changes from jfwood.
Query Server for DB information
Merge pull request #7 from dmend/master
