[MAINT] - Adress flakiness of Integration tests

[viniciusdc]

Context

With the recent adoption of await workflow, which is a blessing since before we needed to include the kubectl command ourself anyways manually, we are getting some weird issues a few times with the image puller; it seems like it got stuck waiting for it in a couple of deployments, looks like a flaky behavior and requires further validation. There may be a need to increase the time limit or retries.

Also, during releases, we have a hard time running CI against version bumps since, by common standard during the release workflow, we don't yet have the new images available, and the deployment fails under the check health status of the pods (namely jupyterhub)

@viniciusdc I think the first case is related to #2947. However, I agree our tests seem to be flaky and that needs to be addressed.
