Title:
  Bridges are configured as physical nic when delivered by
  network_data.json

Status in cloud-init:
  Expired

Bug description:
  Bridges are configured as physical nic when delivered by network_data.json
  network_data.json
  ```...
  links:
  - id: br0
    name: br0
    type: bridge
    bridge_stp: on
    bridge_fd: 0
    bridge_interfaces:
      - underlay0
  ....
  ```
  /usr/lib/python3/dist-packages/cloudinit/sources/helpers/openstack.py
  ```
  ...
  if link['type'] in ['bond']: 
  ...
  elif link['type'] in ['vlan']:
  else:
      if link['type'] not in KNOWN_PHYSICAL_TYPES:
           LOG.warning('Unknown network_data link type (%s); treating as'
           ' physical', link['type'])
      cfg.update({'type': 'physical', 'mac_address': link_mac_addr})
  ```
  There is no switch for "bridge"
  It replaces type "bridge" with 'physical'

  To solve this
  ```
  elif link['type'] in ['bridge']:
    params = {}
    for k, v in link.items():
      if k == 'bridge_interfaces':
        continue
      elif k.startswith('bridge'):
         params.update({k: v})
      cfg.update({'params': params,
                'bridge_interfaces': link['bridge_interfaces']})
  ```
