### Problem to solve The GKE integration doesn't seem to validate cluster name when creating a new cluster. This may lead to the elusive `Something went wrong while creating your cluster on Google Kubernetes Engine Failed to request to CloudPlatform; Invalid request` error. For example, a cluster name that starts with a number will fail to create. Only by creating the cluster in GCP we see that this trips a validation. ### Proposal Validate cluster name according to GCP's guidelines: >Name must start with a lowercase letter followed by up to 40 lowercase letters, numbers, or hyphens, and cannot end with a hyphen ### Links / references ZD: https://gitlab.zendesk.com/agent/tickets/96476 (internal)
