## What As well as https://github.com/terraform-providers/terraform-provider-google/pull/1282 , make `resource_container_node_pool` importer accept `{project}/{zone}/{cluster}/{name}` format to specify the project where the node pool belongs to actually. ## Why Sometimes I want to import container pool in different project from default SA's. However, currently there is no way to specify project the target node pool belongs to, Terraform tries to retrieve node pool from SA's project, then it fails due to `You cannot import non-existent resources using Terraform import.` error.
