Highlights for the week ending 2021-03-12

What does this Merge Request do?

This MR updates CHANGELOG.md to include highlights for the week ending 2021-03-12. Here's the expanded version:

Promote auto_reconfigure to stable and default enabled !1873 (merged)

Having gdk reconfigure auto run as part of a gdk update has been available as an experimental feature for some time but it was disabled by default. This MR promotes the setting to be stable and enabled by default so gdk reconfigure will auto run as part of a gdk update now.

Run workhorse from gitlab/workhorse !1808 (merged)

The gitlab-workhorse GDK service previously ran out of GDK_ROOT/workhorse but now runs out of GDK_ROOT/gitlab/workhorse and comes from https://gitlab.com/gitlab-org/gitlab/-/tree/master/workhorse. There is no expected compatibility issues going forward, other than a GDK_ROOT/workhorse directory remaining.

Thanks @jacobvosmaer-gitlab ❤

Add Reviewer Roulette for the GDK project !1863 (merged)

Reviewer roulette is now enabled for the GDK project for all MRs 🙂 Currently the roulette logic is simply copied across from gitlab-org/gitlab and modified but gitlab!36464 (merged) will extract the logic out into a gem for all to use 🙂

Make jaeger no longer enabled by default !1874 (merged)

For most users, jaeger is not required so it is now disabled by default. There is no impact if you had it explicitly enabled.
