added mvc controller method to clear the OAI caches: oai/clearCaches.do

Cache management: it's a mess if we have more than one <cache:annotation-driven> instructions:
- the container now has a dedicated application context for caches
- logs to DEBUG for spring cache module

#1342: added caches to limit the load on exists when a client performs a list of getRecord requests.

StringUtils.split does not add empty strings in the resulting array, but I do need them, hence I use the native String split function.

Do not encode the resumption token #1310

RecordInfo with provenance.

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

updating to major release of ServiceLocator

Not counting even for date range queries. OAI requests with date ranges are served without the information about the completeListSize.

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