Subject: Handle bootstrap behavior in GCP template
Allow each node group to request bootstrap, allow per node group image
override, and ensure the provision logic does not wait for bootstrapping
node groups before continuing.
This is an incremental step to allow GCP clusters to use bootstrap logic
on cluster deploy without having fully baked images. We will switch over
slowly and ensure both code paths function.
