ISPN-5032 Remove excessive logging from GetKeyValueCommand
BaseDistSyncL1Test doesn't need AFTER_METHOD test cleanup
ISPN-5032 Create a GetCacheEntryCommand to remove the "fetchEntry" modification flag from GetKeyValueCommand
ISPN-5038 Remote package refactor
ISPN-5072 MapExternalizer no longer needs to extend
InstanceReusingAdvancedExternalizer

* Changed which class extends Reusing Externalizer
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging
writes to log4j in the cdi module (and dependents).

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
