Allow Package Specification for Configured Properties

[aclifford85]

To uniquely specify a property when two components exist with the same name but in different packages.
e.g.
service.webserivces.v1.myService.property1=v1-property
service.webserivces.v2.myService.property1=v2-property

Or to simplify reverse trace the package name e,g.

v1.myService.property1=v1-property
v2.myService.property1=v2-property
