GCP: Refactor data disk(s) creation and setup to instance template v2 (#537)
* Add roles to create and delete empty image (workaround) GCE API does not allow you to specify empty disks in instance templates. This is a workaround to that limitation. The version of cloudilb currently available as an RPM on my build system also doesn’t allow me to specify a family for this image. The impact of this is limited because GCE API has a bug where as if we specify the image using the family it doesn’t work as expected. * Refactor disk creation to instance templates There is currently a bug in GCE API that when you specify a non-boot disk sourceImage as a family it will instead use the sourceImage from the boot disk. To workaround this we don’t use a family to specify this sourceImage even though it is more appropriate to do so. * Instance group related pauses We introduce two pauses: 1) Immediately after creating the “core” deployment. This is to give time to the instance groups to become “complete”. Ideally we would poll the API instead of waiting a fixed amount of time but this is better than nothing. 2) The second waits for the newly spawned instances to be reachable. Ideally we would use wait_for_connection to achieve this but the following bug keeps this from working for instances behind a bastion host: https://github.com/ansible/ansible/issues/23774 * Use cloud-init to configure attached data disks * Cosmetics cleanup, removed some values which are default.. Also let's forget about empty image family, no need to version this image. * Query instance group manager to see if instances are ready * Empty image archive is very small, no need for composite upload * Use more robust check if instances are ready for ssh
