A lot has changed in Octavia since the parapgrahs this patch touches on
were written. We should encourage operators and end-users to use Octavia
as first-class load balancing solution in OpenStack rather than
misleading new users by recommending them to use Neutron LBaaS with
Octavia as provider driver, at least whenever possible. A note is left,
though, for operators and end-users already running Neutron LBaaS to
migrate either to Octavia or, if not immediately possible, use the
Octavia proxy plugin in neutron-lbaas.
