[cloud-gce] replace integration tests by unit tests

We use google transport mock as we can simulate whatever JSON answer GCE platform will send us and really test Gce implementation.

We also remove GceSimpleITest as the goal of this class was only to check that when we start elasticsearch with this plugin, elasticsearch works fine.
We don't need that anymore as we now have RestIT which do that right (and better)!

Closes #12622

 way to alter these permissions is to delete the instance (NOT THE DISK). Then create another with the correct permissions.
 
 
-Testing
-=======
-
-Integrations tests in this plugin require working GCE configuration and therefore disabled by default.
-To enable tests prepare a config file elasticsearch.yml with the following content:
-
-```
-cloud:
-  gce:
-      project_id: es-cloud
-      zone: europe-west1-a
-discovery:
-      type: gce
-```
-
-Replaces `project_id` and `zone` with your settings. 
-
-To run test:
-
-```sh
-mvn -Dtests.gce=true -Dtests.config=/path/to/config/file/elasticsearch.yml clean test
-```

+ * This test class uses a GCE HTTP Mock system which allows to simulate JSON Responses.
+ *
+ * To implement a new test you'll need to create an `instances.json` file which contains expected response
+ * for a given project-id and zone under the src/test/resources/org/elasticsearch/discovery/gce with dir name:
+ *
+ * compute/v1/projects/[project-id]/zones/[zone]
+ *
+ * By default, project-id is the test method name, lowercase.
+ *
+ * For example, if you create a test `myNewAwesomeTest` with following settings:
+ *
+ * Settings nodeSettings = Settings.builder()
+ *  .put(GceComputeService.Fields.PROJECT, projectName)
+ *  .put(GceComputeService.Fields.ZONE, "europe-west1-b")
+ *  .build();
+ *
+ *  You need to create a file under `src/test/resources/org/elasticsearch/discovery/gce/` named:
+ *
+ *  compute/v1/projects/mynewawesometest/zones/europe-west1-b/instances.json
