public CacheFactory setPostProcessor(PostProcessor postProcessor) {

Sets the postProcessor for the cache. If this postProcessor is set, it will override the
security-post-processor setting in the gemfire system properties.

This is provided mostly for container to inject an already initialized post processor. An
object provided this way is expected to be initialized already. We are not calling the init
method on this object

@param postProcessor the postProcessor for the cache
