Cache management: it's a mess if we have more than one <cache:annotation-driven> instructions:

- logs to DEBUG for spring cache module

RecordInfo with provenance.

Fixed xqueries and methods to get the id namespace and scheme.

updating to major release of ServiceLocator

idScheme and idNamespace are not a property anymore, but they are dynamically read from the OAI configuration profile

Cleaned logs
