Migrate deployment-prep away from Debian Stretch to Buster/Bullseye
Open, Needs TriagePublic

Description

Jessie has now been removed from deployment-prep (just about 1 year and 4 months after the deadline, let's try to be faster this time). As production starts moving away from Stretch, it's time for us too to start removing Stretch instances.

Few notes:

As of 2020-03-28, the following deployment-prep instances are on Stretch:
