Add a new key class which uses @GeneratedValue to base classes

This will provide an alternative unique key.
It will be used in place of PfTimestampKey in the PdpStatistics table.
We make use of the @GeneratedValue annotation to provide this feature.
Added DummyGeneratedIdEntity and unit tests
Added PfFilterFactory class
Added new filter classes
