You can download the specific version from launchpad: https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/21811814 (I don't think there's an APT repository you can use for this, but I might be wrong)
What I ended up doing after the quick'n dirty downgrade workaround though is to switch to the mariadb client instead, which is in the repo and can connect to Azure MySQL without any issues.
