Standardize disabling cloud-init on non-systemd (#2112)

Some distros support disabling cloud-init using the 
kernel argument cloud-init=disabled. Standardize it
across non-systemd distros. Skip NetBSD, which
doesn't support passing external arguments to the
kernel.

Also add support for disabling cloud-init using
/etc/cloud/cloud-init.disabled to non-systemd
distros.
