DATAVK-86 - Improved auto-template-registration infrastructure.

KeyValueRepositoryConfigurationExtension now need to report the default value for the KeyValueTemplate reference. We now only register a default template if the reference has not been customized. Changed the default reference value for Maps to mapKeyValueTemplate to allow individual defaults per store.

Removed obsolete RepositoryNamespaceHandler.
