#2188 RBAC issues with fabric-cxf-registry
first spike of #2189 to lookup dynamically the metatype from the available bundles in a profile
create a mvn plugin to generate build time metatype for all the known bundles at build time
#2189 use the fabric8:copy-metatype plugin to copy the metatype metadata into the distro
#2189 fixed up the mvn plugin and runtime introspector so it finds the correct properties file to perform i18n and the mbean now defaults to loading metatype from the distro for stuff not on a profiles classpath (e.g. for java / process containers)
#2189 added the MBean API to access the metatype object definition for any profile/version even if its not running or has any OSGi runtime
