CI/review_apps: Make use of external-dns and ephemeral IPs

Closes #7683

See merge request gitlab-org/gitlab-ee!7443

Prune all the Geo event log tables correctly

Closes #6422

See merge request gitlab-org/gitlab-ee!6175

Don't rely on static IPs for Ingress/LoadBalancers. To do this, we
implement annotations for `external-dns` to be able to populate
endpoints into our `$REVIEW_APPS_DOMAIN`.

This requires the installation of `external-dns` into the cluster
used by CI, which is not a part of this MR.

See #7683 comments for details of installation.

Remove duplicated code in Geo event store specs

See merge request gitlab-org/gitlab-ee!7418

CE upstream - 2018-09-20 00:21 UTC

Closes gitlab-ce#51380

See merge request gitlab-org/gitlab-ee!7420

This introduces a shared example that encapsulates the common
behavior present in the parent class removing the duplicated
code in the specs.

The 9.4 to 9.5 and 9.5 to 10.0 guides missed a closing backtick. This
was corrected in the 10.0 to 10.1 guide, from which subsequent guides
were written without the error.

Due to a missing `s`, a link to the blog archive
for releases was broken.
