Add link to cluster detail page in GKE to view cluster creation status while creating a cluster via GitLab

Problem to solve

When provisioning a K8s cluster via GitLab on GKE it takes a while before the cluster is ready. During this time there is no detailed feedback on the status or progress of the cluster creation and the only way to see it is to view the cluster page in GKE.

Further details

To see the actual status of cluster creation you currently have to go into GKE to see the status (or any errors if any occur).

Proposal

Add a link to the cluster page in GKE as part of the notification that allows a user to see the status of their cluster.

The link to the cluster will be in the following form: https://console.cloud.google.com/kubernetes/clusters/details/$REGION_ID/$CLUSTER_NAME?project=$GCP_PROJECT_ID

Proposed notification wording: Kubernetes cluster is being created on Google Kubernetes Engine. View cluster creation status.

Where View cluster creation status is the link to the cluster detail page.

What does success look like, and how can we measure that?

The user should be able to click on a provided link to go directly to cluster details page in GKE so they cans ee the status of the cluster creation.
