OCM-10640 | ci: Fix destroy resources if error in apply

[radtriste]

What this PR does / why we need it: In e2e tests, if an error occurs during apply, some resources may have been created already. But the TF vars file is not saved, thus the destroy will not occurs. This fix is storing the values in a tfvars tmp file and destroy will consider it if existing if the default TF vars file is not existing.
