Allow selection of VPC native when creating GKE Cluster in GitLab
Problem to solve
GKE has enabled VPC-native cluster creation a couple months ago, easing a lot the integration with other Google Cloud Services. There is no way in GitLab UI to create a cluster with this feature enabled, and it can't be enabled after creation, leaving no choice but creating the cluster manually on GCE and add it manually.
Provide a checkbox in cluster creation page to enable VPC-native cluster.
