Upgrade to Gradle 6.0 (#49211) (#49994)

This upgrade required a few significant changes. Firstly, the build
scan plugin has been renamed, and changed to be a Settings plugin rather
than a project plugin so the declaration of this has moved to our
settings.gradle file. Second, we were using a rather old version of the
Nebula ospackage plugin for building deb and rpm packages, the migration
to the latest version required some updates to get things working as
expected as we had some workarounds in place that are no longer
applicable with the latest bug fixes.

(cherry picked from commit 87f9c16)
