Carlos Goncalves 89de63de05 Port data plane status extension implementation
Implements the port data plane status extension. Third parties
can report via Neutron API issues in the underlying data plane
affecting connectivity from/to Neutron ports.

Supported statuses:
  - None: no status being reported; default value
  - ACTIVE: all is up and running
  - DOWN: no traffic can flow from/to the Neutron port

Setting attribute available to admin or any user with specific role
(default role: data_plane_integrator).

ML2 extension driver loaded on request via configuration:

  [ml2]
  extension_drivers = data_plane_status

Related-Bug: #1598081
Related-Bug: #1575146

DocImpact: users can get status of the underlying port data plane;
attribute writable by admin users and users granted the
'data-plane-integrator' role.
APIImpact: port now has data_plane_status attr, set on port update

Implements: blueprint port-data-plane-status

Add ``data_plane_status`` attribute to port resources to represent the
status of the underlying data plane. This attribute is to be managed by
entities outside of the Networking service, while the ``status`` attribute
is managed by the Networking service. Both status attributes are independent
from one another.
features:
- The port resource can have a ``data_plane_status`` attribute.
Third parties can report via Neutron API issues in the underlying data
plane affecting connectivity from/to Neutron ports.
Attribute can take values ``None`` (default), ``ACTIVE`` or ``DOWN``,
and is readable by users and writable by admins and users granted the
``data-plane-integrator`` role. Append ``data_plane_status`` to
[ml2]/extension_drivers section to load the extension driver.
