* feat (tests): Adding initial set of tests for REST

Related to primeqa#357

* fix (IndexingService): Update getIndexes API to only return based on engine type.

* fix (reader): Updating reader proto and removing generative reader from factory.

* skip hybridqg tests to allow CI to run to completion
