Critical bugs for 1.20.

[Curtis Hovey-Canonical]

We are tracking a list of critical bugs that must be fixed to release 1.20.
    https://launchpad.net/juju-core/+milestone/1.20.0

I intend to create a 1.20 branch in
    https://github.com/juju/juju
that we can merge fixes into. Actually I have done that, but github
doesn't want me to merge by version branch...I need to tinker with the
issue to resolve it.

I think the 1.20 branch needs to be version 1.20.0
I propose we set the master branch to 1.21-alpha1 now so that
development can continue to add new features.
