Description of problem:

Sometimes oVirt installer fails due to terraform error:
```
level=debug msg=2021-01-22T22:22:44.534Z [DEBUG] plugin.terraform-provider-ovirt: 2021/01/22 22:22:44 [DEBUG] Failed to wait for Templte(efcb7a8f-8f61-46d0-be46-9ba0d1170d82) to become ok: couldn't find resource (21 retries)

level=error msg=Error: couldn't find resource (21 retries)
level=error
level=error msg=  on ../tmp/openshift-install-088314764/template/main.tf line 78, in resource "ovirt_template" "releaseimage_template":
level=error msg=  78: resource "ovirt_template" "releaseimage_template" {
level=error
level=error
level=fatal msg=failed to fetch Cluster: failed to generate asset "Cluster": failed to create cluster: failed to apply Terraform: failed to complete the change
```

I saw it while there was huge pressure on CI, notice that the timeout hire is 4m[1], maybe worth trying to increase it.
