packer is useless without builders (lxd)

[anatoly techtonik]

There are no plugins shipped with packer. Not even lxd, which is kind of official Ubuntu proposition. Running example template from here - https://www.packer.io/docs/builders/lxd.html - gives the following:

    $ packer build example.json
    Failed to initialize build 'lxd-xenial': builder type not found: lxd
    lxd-xenial output will be in this color.

    ==> Builds finished but no artifacts were created.

The example:

{
  "builders": [
    {
      "type": "lxd",
      "name": "lxd-xenial",
      "image": "ubuntu-daily:xenial",
      "output_image": "ubuntu-xenial",
      "publish_properties": {
        "description": "Trivial repackage with Packer"
      }
    }
  ]
}
