Description

We used the terraform to enable the container expiration policy. After deciding to back out of this decision, it is not possible to disable the container expiration policy via the provider. Even though the plan shows the correct change, applying the change has no effect. The policy still shows enabled in the UI and a subsequent tf plan shows the same outstanding changes.

I can disable the policy just fine via the UI and API, but the tf provider is definitely broken when it comes to setting disabling the policy.

It seems like this was possibly discovered initially here: https://github.com/gitlabhq/terraform-provider-gitlab/issues/1039
