Removed the XSD enumeration restriction on the 'type' attribute of the 'evictionType' XSD complex-type definition in the SDG XML namespace schema, which is used by the 'eviction' sub-elements in the LOCAL, PARTITION and REPLICATE Region element schema types. In addition, created the ExpirationAttributesFactoryBean class in the org.springframework.data.gemfire package which serves as a Spring FactoryBean and builder for constructing GemFire EvictionAttributes used in Region configuration. Updated tests to assert and validate the use of property placeholders on both the Eviction 'type' and Expiration 'action' attributes in the Spring Data GemFire XML namespace configuration meta-data.
