whether needing to modify all ManagedServiceFactory's SERVICE_PID in order to allign with jclouds group id's change

This is a very trivial issue, eg. jclouds-karaf\services\src\main\java\org\jclouds\karaf\services\internal\Activator.java,

properties.put(Constants.SERVICE_PID, "org.jclouds.compute");

Whether should also modify "org.jclouds.compute" ---> "org.apache.jclouds.compute"?

Although not modifying it does not cause any issue.

In addition, a suggestion is that we'd better not use hardcoding("org.jclouds.compute") scattering in different source file. Instead, placing and grouping them into a file.
