Add ability to filter types de/serialized by the o.s.d.g.mapping.MappingPdxSerializer

Currently, SDG's o.s.d.g.mapping.MappingPdxSerializer does not filter by type when de/serializing, types which are determined by Pivotal GemFire's serialization functionality to be handled by by the MappingPdxSerializer when transferring data, messages, configuration or other types of objects during the normal operation of Pivotal GemFire.

This is in contrast to Pivotal GemFire's own o.a.g.pdx.ReflectionBasedAutoSerializer, which accepts a Regular Expression expressing the (limited) types to be explicitly handled by the PdxSerialzier.

This JIRA would enable users to employ a similar strategy/capability.
