f832f1073d47a430111c59563962922dfe37a0a5 addressed LP: #1635067 by
adding support for using pre-created Linux bridges in the data-port
config option.
The same use-case of reusing a single physical interface for VLAN
interfaces and plugging it into an OVS bridge can be addressed in a
different way by plugging the physical interface directly into the OVS
bridge and creating VLAN interfaces on that physical interface - this
does not require the use of veth pairs which is problematic due to the
performance reasons and lack of support for in netplan for veth pairs at
the time of writing.
There is a procedure to move from the setup with Linux bridge and veth
pair used to the one that does not which will be documented to migrate
the existing environments in-place.
