[WIP] Support both 2.9 and 3.x at the same time

[cderici]

Description

Uses both schemas to generate clients that have code to support both 2.9 and 3.x facade functionality at the same time (no need to keep separate sets of client files and dynamically check -- like we did in 3.0.4 to do this).

Adds a separate integration tests against 2.9, let's see which functionalities are gonna blow up, then we'll continue from there.

Hey @jneo8, not really tbh, we have way more things having higher priority right now in Juju.

If you're having trouble migrating from 2.9 to 3.x feel free to reach out at Juju channel on Matrix.

We just want to know if python-libjuju can support this in a short time(6 months) to make the technical decision.

Thanks for reply.
