Lifecycle Rules in Module

[mark-aops]

We are using the Autoscaler for Spanner so terraform conflicts if the scaler sizes the instance differently from the module. Please include a variable for lifecycle block. Something like:

dynamic "lifecycle" {
  for_each = var.ignore_processing_units ? [1] : []
  content {
    ignore_changes = [processing_units, num_nodes]
  }
}
