Renaming of BundleResource APIs

Renaming of BundleResource APIs

Renamed the BundleResource APIs from simple setAttribute and getAttribute to
handleSetAttributeRequest and handleGetAttributeRequest. The maintainer
of the primitive services prefers these names in order to avoid
confusion with other resource encapsulation APIs.
The plain setters and getters are just for basic data structure manipulation and
do not handle any bundle resource specific logic any more.
