QPID-2581 : Update ConfigurationPlugin to correctly handle attributes in configuration.

Added work around for the fact that we use a Composite Configuration that turns an XML attribute key of '[@attribute]' in to '@attribute]'. Added test for to this conversion.

This makes the Plugin Configuration interface consistent so if we swap our configuration format. The key style of '[@attribute]' will work as expected.
