SGF-211: Allow PPH for partitioned-region copies
Merged pull request #30 from dturanski/SGF-211. In addition, added additional test cases to verify that the underlying GemFire PartitionAttributesFactory validates the value of the 'redundantCopies' property before creating the PartitionAttributes instance given the type for the 'copies' attribute on the basePartitionedRegionType in the SDG XML Schema was changed from a byte to a string and the type restrictions (0-3) on the value were lifted.
