needs special handling when installing to ROOT (under Tomcat)

[kares]

... or a control parameter whether to extract the .war

killbill:
  version: 0.12.1
  webapp_path: /var/lib/tomcat7/webapps/ROOT
  plugins_dir: /var/tmp/bundles

simply created a killbill-xxx.war file under the ROOT directory (which is no a valid / deployment) instead of extracting the .war content there ... scenarios where the .war is renamed would likely be also interesting on some servers (have not tried) e.g. /var/lib/tomcat7/webapps/ROOT.war
