#1195 fixed up features file
#1195 refactored the container profiles to avoid the unnecessary docker folder; so they work both with docker and child container providers; also moved away from environment variables to using io.fabric8.container.java PID by default so its easier to tool the configuration UI via OSGi MetaType
#1195 ProcessControllerFactory reference should be optional and dynamic
#1195 updated to the latest felix SCR plugin; so we get nicer generated metatype resource bundles and don't have to add @Property(name="...") where name is the name of the field
#1195 polished metatype metadata
