Bug Description
We recently disallowed *any* Juju downgrades because the addition of better upgrade support meant that going from 1.X to 1.X+1 may introduce changes to conf and other artefacts that are no longer able to be read by the earlier version. So allowing a downgrade would break Juju.
However, we want to allow downgrades to the same major.minor version number eg from 1.2.3 to 1.2.2. This allows our CI testing to continue to work with the existing test scripts and also allows customers to downgrade to an earlier patch level if required.
