GCP, OS Login, and Ansible

#### Overview of the Issue

I'm trying to enable OS Login on a previously working Packer + Ansible setup.

It appears that when you use the Ansible `user` task for the user packer is using in the Ansible provisioner, login breaks.

#### Reproduction Steps

Put the files below in the same directory and run `packer build packer.json`
There are a few variables that you may want to change.

If you remove either of the following... the image will build
- the OS Login lines
- the `user` field in the provisioner

### Packer version

Packer v1.7.4
