Adds support for the `Ironic Inspector dnsmasq PXE filter
<https://docs.openstack.org/ironic-inspector/latest/admin/dnsmasq-pxe-filter.html>`__
that provides improved scalability over the default IPTables PXE filter.
This is now used by default instead of the ``iptables`` PXE filter.
The ``iptables`` filter can be enabled by setting
``ironic_inspector_pxe_filter`` to ``iptables``.
upgrade:
- |
The default PXE filter used by Ironic Inspector is now ``dnsmasq`` rather
than ``iptables``. This change has been made to work around an issue
introduced by moving to Docker CE, where the daemon sets the default
policy on the ``iptables`` ``FORWARD`` chain to ``DROP``. This policy can
interact with the Ironic Inspector ``iptables`` PXE filter to cause DHCP
packets from bare metal nodes to get dropped, which prevents provisioning.
