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

notes:
- 'API Reference: U(https://cloud.google.com/compute/docs/reference/rest/v1/nodeGroups)'
- 'Sole-Tenant Nodes: U(https://cloud.google.com/compute/docs/nodes/)'
- 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)
