    - 'This field represents a link to a Model resource in GCP. It can be specified
      in two ways. First, you can place a dictionary with key ''name'' and value of
      your resource''s name Alternatively, you can add `register: name-of-resource`
      to a gcp_mlengine_model task and then set this model field to "{{ name-of-resource

    type: str
notes:
- for authentication, you can set service_account_file using the C(gcp_service_account_file)
  env variable.
- for authentication, you can set service_account_contents using the C(GCP_SERVICE_ACCOUNT_CONTENTS)
  env variable.
- For authentication, you can set service_account_email using the C(GCP_SERVICE_ACCOUNT_EMAIL)
  env variable.
- For authentication, you can set auth_kind using the C(GCP_AUTH_KIND) env variable.
- For authentication, you can set scopes using the C(GCP_SCOPES) env variable.
- Environment variables values will only be used if the playbook values are not set.
- The I(service_account_email) and I(service_account_file) options are mutually exclusive.
