[Automation] - Adding data state cleanup before running cloud-credential spec

[izaac]

Summary

Fixes https://github.com/rancher/qa-tasks/issues/1335

Occurred changes and/or fixed issues

Adding a cleanup step to the Cloud Credential spec. This will ensure the initial state of the cloud credentials data is always empty on retries.

Areas or cases that should be tested

I've tested the remove when there are credentials linked to a cluster. I left the API check out to avoid collisions with the provisioning tests.

Areas which could experience regressions

E2E tests. Provisioning and Cloud credentials. Low risk.
