Enable the configuration of content manager root folder through system property
The only way to configure the root folder where File based Content Manager will store the content is through the configuration file. However, the path is that folder is resolved relatively, and by default if it contains data/content the absolute path will not be the same for karaf and tomcat.
It would be good to have a -DcontentManager.rootFolder=${weblab.home}/data/content in the configuration.xml so that it can be resolved to the same path in both karaf and tomcat
