Backports of "Remove feature flag behind MR's multiple assignees"

See merge request gitlab-org/gitlab-ce!30261

When opening the IDE on a project where the user doesn't have push
access, we create a fork and then redirect back to the IDE. To make
sure the user can actually commit, we need to open the IDE in the forked
project rather than the upstream project.

Pin the version of deployed external-dns to `2.y.z`, using SemVer
matching. (`^2.2.1`)

Update the properties for the service account keys per
*Upgrading to 2.0.0* of the `stable/external-dns` README.

Add `aws.batchChangeSize=400` to combat messages about RDATA being
too large.
