This change also introduces two network interfaces:
* flat: Copies current neutron DHCP provider logic to work with
cleaning ports;
* noop: noop interface.
The default value of the network_interface is None, meaning that the
node will be using the default network interface. The default network
interface is determined the following way:
* if [DEFAULT]default_network_interface configuration option is set
(the default for it is None), the specified interface becomes the
default for all nodes;
* if it is not set, 'flat' interface will be used if the deployment
currently uses 'neutron' DHCP provider, otherwise 'noop' interface
will be used.
create_cleaning_ports and delete_cleaning_ports methods of the DHCP
providers are still being called in case of out-of-tree DHCP
providers, but this possibility will be removed completely in the
next release. If the DHCP provider logic is rewritten into a custom
network interface, please remove those methods from the provider, so
that network interface is called instead.
