ubuntu user doesn't have password-less sudo on centos7

[james beedy]

The ubuntu user doesn't seem to have password-less sudo on centos7 deployed on a localhost/lxd cloud.

This was reported by one of our developers, I just verified on a fresh controller.

The centos7 image was provisioned following the documentation https://omnivector-solutions.github.io/osd-documentation/master/installation.html#centos7-deploys-on-lxd-clouds

$ juju add-machine --series centos7

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for ubuntu:

I just verified that the ubuntu user does have passwordless sudo on centos7 deployed via MAAS. It seems this issue only exists for lxd deploys as far as I can tell.

We could add the user to /etc/sudoers with NOPASSWD when running the userdatacfg.

@simonrichardson - I hadn't been back around to this bug until just now. This is great! How can we do this?
