Upgrade servers to Ubuntu 22.04

[ghost]

Ubuntu 22.04 is available on Linode.
I am not expecting many changes to our Salt code as it is quite similar to 20.04. We will need to update documentation for the new version.

Currently there are bugs in SaltStack preventing deployments to 22.04 servers, these need resolving before we can move forward with upgrades.
This bug in-particular completely breaks our use of pkgrepo, saltstack/salt#59065

This will supersede the 20.04 server upgrades #145

Change the Ubuntu and Python #346 versions in GitHub Actions workflows:

• kingfisher-collect
• kingfisher-process
• kingfisher-summarize

There are PRs for our blocking issues:

• Fix pkgrepo.managed PPA handling for newer Ubuntu versions saltstack/salt#63157 for [BUG] pkgrepo.managed fails to configure ppa on Ubuntu 20.10 saltstack/salt#59065 (pkgrepo)
• Explicity pass context for salt-ssh state calls saltstack/salt#63184 for [BUG] salt-ssh support for extra_filerefs in Saltfile is broken saltstack/salt#60003, which was keeping us locked to salt-ssh<3003
  • This seems to work now. Tested on redash and cove-*.

According to the 3005 release notes (Aug 2022), Ubuntu 22.04 is supported.

Note that Salt is changing to a "one-dir" packaging approach for future releases.

Also, if using macOS, new versions of salt-ssh require Python 3.9 or 3.10. Previously, I couldn't even install new versions of salt-ssh, because of its dependency on pyobjc. This was fixed in 3005.

Note: https://docs.saltproject.io/salt/install-guide/en/latest/topics/upgrade-to-onedir.html

The current onedir packages for 3005.1 do not support ARM64, but ARM64 will be supported in the next major release.

I attempted to install via https://docs.saltproject.io/salt/install-guide/en/latest/topics/install-by-operating-system/macos.html#install-macos but then I figured out how to get the pip installation working.

Okay, I succeeded in upgrading Salt in requirements.txt so that I can use it locally on Python 3.10, macOS Ventura.

I don't have an Ubuntu 22.04 server to test on. I was able to deploy to 18.04 and 20.04 servers using PPAs and filerefs.

Noting that I referenced a couple issues in specific applications that will be unblocked by this issue.

It looks like we already updated relevant documentation.

Since we've been deploying to Ubuntu 22, it seems the above issues are no longer blockers.

I've moved the Ubuntu and Python changes in project workflows to #402.
