Please support creating openvswitch bridges

[greenmoss]

From the MaaS UI, we can create openvswitch bridges. However, we can not from python-libmaas.

I am using python-libmaas from master of this git repo, dated 2023-10-23, commit fec3b5023f9d618ba61e9d9108a345300216d8c3.

Example:

>>> machine.interfaces.create(maas.client.enum.InterfaceType.BRIDGE, name='br0', parent=interface, bridge_type='ovs')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    result = eventloop.run_until_complete(result)

I think this would be a good addition. I also always use OpenVSwitch bridges.
