ISPN-4639 IndexingConfigurationBuilder query module validation is wrong

* Added new validate method that provides access to GlobalConfiguration
* Changed IndexingConfigurationBuilder to use GlobalConfiguration CP
* Added Clustering validations to ensure transport is set

From your response I take it you are suggesting to add the method only to the ConfigurationBuilder then, correct?  To be honest neither this way or adding the method seems very appealing yet :(
