Title: Fix support for allow-hotplug statement in debian_ip network module

When an existing interface was configured with `allow-hotplug` or when setting
`hotplug: True` in network.managed state, this was not taken into account and
the `allow-hotplug` setting would be removed from /etc/network/interfaces.

This patch fixes this issue.
