Description

Azure won't support Ubuntu 16.04 starting from October, hence we need to migrate to a newer ubuntu version.

We should do this at a time when the builds are relatively stable to be able to clearly identify issues relating to the version upgrade. Also, we shouldn't do this before a feature freeze
