Warning: Bundled plugins used
This template relies on the use of plugins bundled into the Packer binary.
The practice of bundling external plugins into Packer will be removed in an
upcoming version.
To remove this warning and ensure builds keep working you can install these
external plugins with the 'packer plugins install' command
* packer plugins install github.com/hashicorp/azure
* packer plugins install github.com/hashicorp/amazon
* packer plugins install github.com/hashicorp/googlecompute
