Create auto-generated objects.go file (infobloxopen#178)

This branch contains newly added object structures of WAPI with generator code , where object_generated.go is created for applying the changes. 

For some fields with omitempty, where some cases with updating empty is not considered as update introduced pointers. 

Added E2E tests for functional validation of objects generated

+# End-to-end tests
+
+This set of tests is intended for functionality validation on an existing WAPI
+instance.
+
+## How to run E2E tests
+
+1. Export parameters of accessible and running `WAPI` instance:
+   ```bash
+   export INFOBLOX_SERVER=<WAPI HOST IP> INFOBLOX_USERNAME=<WAPI USERNAME> INFOBLOX_PASSWORD=<WAPI PASSWORD> WAPI_VERSION=<WAPI VERSION>
+   ```
+
+2. You can use `go test` utility to run the tests in the `e2e_tests` directory:
+   ```bash
+   go test -v ./e2e_tests
+   ```
+
+3. Instead of `go test` you can also use the [`ginkgo`](https://onsi.github.io/ginkgo/#installing-ginkgo) utility, 
+   which supports test filtering by label, and lots of [additional features](https://onsi.github.io/ginkgo/#running-specs):
+   ```bash
+   # Run all e2e tests
+   ginkgo e2e_tests
+   # Run only read-only e2e tests
+   ginkgo --label-filter=RO e2e_tests
+   ```
+
+## Warning
+
+Please don't run those tests on the production WAPI instance.
