Bug Description

The DHCP agent is filled with warnings about networks being deleted. These happen all of the time in a normal lifecycle, they are not warning worthy!

    DHCP: Downgrade 'network has been deleted' logs

    These will happen all of the time as networks are quickly
    created/updated and then deleted. It's not any kind of
    actionable warning condition so this patch downgrades them
    to debug.
