run.googleapis.com/operation-id always triggers updates

[juliodiez]

This metadata annotation in a Cloud Run service always triggers an update-in-place. Investigate what is this for and consider to avoid this behavior in the provider resource, or our module.

Can you put an example here?

After deploying and without doing any change in configuration, another invocation of terraform plan (excerpt):

$ tf plan
Terraform will perform the following actions:
  # module.cloud_run.google_cloud_run_service.service will be updated in-place
  ~ resource "google_cloud_run_service" "service" {
        # (4 unchanged attributes hidden)
      ~ metadata {
          ~ annotations      = {
              - "run.googleapis.com/operation-id"   = "c8ab8803-9055-46fa-9c23-6da2185400b4" -> null

Plan: 0 to add, 1 to change, 0 to destroy.
$

This example suggests the solution is adding a lifecycle block to the google_cloud_run_service resource.
