DATACMNS-456 - Introduced getAttribute(String) on RepositoryConfigurationSupport.

RepositoryConfigurationSupport now has a getAttribute(String) method to lookup String attributes on XML elements and annotations. The XML implementation converts the given attribute name in a lower-case, dashed representation for the lookup.

RepositoryConfigurationExtensionSupport now ha a generic postProcess(…) method to allow implementations that only need to work with String attributes unify their customizations into that single method.
