Avoid cluster creation in GCP

What does this MR do and why?

Describe in detail what your merge request does and why.

Ideally, moving the quarantine bloc to the top level should help avoid creating the resources before the test starts. The line that makes a cluster resource in GCP is now commented to enforce this and avoid ghost clusters starting on an unclean GCP environment. This is a temporary solution until a new environment is created for automated resources.
