GKE Cluster and Type example no longer works

The default GKE cluster version has changed to 1.14.10-gke.17, as a result, the GKE Cluster and Type example in deploymentmanager-samples/examples/v2/gke/ no longer works.
I believe this is a result of the /swaggerapi/* endpoints are deprecated and are removed in Kubernetes 1.14.

A resource snippet was updated in #539 , but even when updating the API endpoint as shown an error occurs when using the deployment part of the example.

`- code: MISSING_METHOD_IN_COLLECTION
message: Method 'insert' does not exist for collection '/api/v1/namespaces/{namespace}/services'
in descriptor url 'https://104.199.106.59/openapi/v2'
`

An updated and working example would be greatly appreciated.
