3rd party should not be affected. Gerrit event stream and reporting
interface remain the same. People should continue using jenkins+zuul as
they currently do. We'll have a full zuul v3 release coming in a few
months where we'll start suggesting 3rd party folks migrate - but even
then it'll be an option as you decide you'd like to.

Yes, ansible-launcher takes care of this. We haven't spent too much time
on more advanced worker management for this release, that should also
come in zuul v3. For right now we're just managing ansible-launcher
nodes as we did jenkins masters before.
