[tc][release] Networking-midonet current status and Wallaby release

The main question is, does the previous Victoria version [1] will be
compatible with the latest neutron changes and with the latest engine
facade introduced during Wallaby?

Releasing an unfixed engine facade code is useless, so we shouldn't release
a new version of networking-midonet, because the project code won't be
compatible with the rest of our projects (AFAIK neutron), unless, the
previous version will not compatible either, and, unless, not releasing a
Wallaby version leave the project branch uncut and so leave the
corresponding series unmaintainable, and so unfixable a posteriori.

If we do not release a new version then we will use a previous version of
networking-midonet. This version will be the last Victoria version [1].

I suppose that this version (the victoria version) isn't compatible with
the new facade engine either, isn't it?

So release or not release a new version won't solve the facade engine
problem, isn't?

You said that neutron evolved and networking-midonet didn't, hence even if
we release networking-midonet in the current state it will fail too, isn't

However, releasing a new version and branching on it can give you the
needed maintenance window to allow you to fix the issue later, when your
gates will be fixed and then patches backported. git tags are cheap.

We should notice that since Victoria some patches have been merged in
Wallaby so even if they aren't ground breaking changes they are changes
that it is worth to release.

>From a release point of view I think it's worth it to release a new version
and to cut Wallaby. We are close to the it's deadline. That will land the
available delta between Victoria and Wallaby. That will allow to fix the
engine facade by opening a maintenance window. If the project is still
lacking maintainers in a few weeks / months, this will allow a more smooth
deprecation of this one.
