Brian C. Lane 0cb4d04479 Lock the root account, except on live-iso
If we leave the root account w/o a password people will use it that way,
leading to insecure images. Also if we use a default password. So lock
the root account in the templates.

Users will need to do one of these things:
 1. Use [[customizations.user]] in their blueprint to configure root or
    another user.
 2. Use [[customizations.sshkey]] to set a key for root
 2. Install a package that configures a user at install time
 3. Install a package that sets up a user at boot time (eg. cloud-init)

This also drops the auth line from the kickstart templates, allowing it
to use the default password algoritm instead of md5.

Resolves: rhbz#1626122
