[bug] Error when redeploying qhub GCP

[viniciusdc]

Describe the bug

When testing qhub on GCP, after enabling DNS auto-provision and succeded deploying qhub, an error occurs when attempting to deploy again with superfluous changes to the qhub-config.

Expected behaviour

Deployment succeeds without any error.

Actual behaviour

It seemed as the state of deployment is not updated since Qhub seems to try to redeploy and recreate the resources as if they do not exist. The following errors are presented once a redeploy is attempted.

[terraform]: │ Error: googleapi: Error 409: Already exists: projects/.../locations/us-central1/clusters/projectname., alreadyExists

[terraform]: │ 

How to reproduce

Fresh instant qhub from main, initialize a GCP deployment, then deploy qhub using the DNS Cloudflare auto-provision setting.
Once the deployment finishes, make a superfluous change to the qhub-config and attempt a second deployment
