automagically apply some spring/default-static-service.xml

[mpo]

For people building pure static-resource modules the current solution requires them to create at least one KAURI-INF/spring/*.xml file to declare a restlet serving the static resources.

This is obvious overkill in such cases: this default behaviour should be automatically applied.

Question remains though when this should be triggered. Possibilities:

1. no KAURI-INF/spring/*.xml file is found and thus some default will be used
2. explicit enabling/disabling this kms-export in the kauri.xml deployment scenario
3. other?
