Merge ~smoser/cloud-init:fix/1404745-growfs-freebsd-y into cloud-init:master

[Scott Moser]

FreeBSD: Invoke growfs on ufs filesystems such that it does not prompt.

By default, FreeBSD's growfs runs interactively asking a question
which can be mitigated using the '-y' command line option. The fix
here is simply to pass -y to growfs to avoid the prompt.

LP: #1404745
