We are injecting manifests into the cloud-init file. The VMs need to be recreated when this file changed. This PR md5 hashes the user data. We also add
lifecycle.create_before_destroyto the VMTemplate and node pool. This has the effect of almost eliminating cluster downtime when changing the bootstrap manifests. The bootstrap manifests are applied to the master node pool so applications should have zero downtime with this change. Fixes #5
