Code Issues Proposed changes

Add network interface to base driver class

Browse Source 
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.

---
features:
- |
Added network interface. Introduced two network interface implementations:
``flat``, which replicates the flat network behavior present previously and
``noop`` when neutron is not used, which is basically a noop interface.
The network interface is used to switch network for node during
provisioning/cleaning. Added ``enabled_network_interfaces`` option in
DEFAULT config section. This option defines a list of enabled network
interfaces on the conductor.
deprecations:
- |
``create_cleaning_ports`` and ``delete_cleaning_ports`` methods in DHCP
providers are deprecated and will be removed completely in the Ocata
release. The logic they are implementing should be moved to a custom
network interface's ``add_cleaning_network`` and
``remove_cleaning_network`` methods respectively. After that, the methods
themselves should be removed from DHCP provider so that network interface
is used instead. ``flat`` network interface does not require
``[neutron]cleaning_network_uuid`` for now so as not to break standalone
deployments, but it will be required in the Ocata release.
upgrade:
- |
``[DEFAULT]default_network_interface`` configuration option is introduced,
with empty default value. If set, the specified interface will be used as
the network interface for nodes that don't have ``network_interface`` field
set. If it is not set, the network interface is determined by looking at
the ``[dhcp]dhcp_provider`` value. If it is ``neutron`` - ``flat`` network
interface is the default, ``noop`` otherwise.
