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

not sure if it is a good idea. I think most children has other children and you may forgot to invoke the validate in the last ones.
