Parent task to keep track of issues and schedule of superset upgrades.
Current version deployed: `0.28.1`26.3`
Outstanding issues:
* From version 0.28.1 onward Superset requires Python 3.6, ~~a version not present in Debian Stretch (max 3.5). We circumvented the issue for 0.28.1 simply building our own Superset python wheel reverting the Python 3.6 check (that was causing the build to fail on 3.5), but this fix might not be possible for 0.29.0+ since upstream started to use constructs like f-strings (only available on Python 3.6).
* Debian Buster (next stable release, it contains Python 3.6) is still under testing,~~. the SRE team has a goal for next Q to start testing it before the Debian Freeze period (to send bugs beforehand etc..). We agreed with SRE that Superset is a good candidate for Buster testing, so the next upgrade will probably be when Buster is available in our production environmentThe SRE team introduced a special apt component to have Python 3.{6,7,8} on stretch with https://gerrit.wikimedia.org/r/#/c/operations/puppet/+/480041.
* Version 0.28.1 introduced several bugs that affect the UI experience, that hopefully should be fixed with 0.29.X
