Legacy feature flags have been deprecated for a while now. The beginning
of the removal process is to stop sending them entirely.

This is gated behind 2 feature flags: `remove_legacy_flags` and
`remove_legacy_flags_override`.

The former is the "main gate" to disable sending legacy feature flags.
The latter is an override control to enable for specific projects that
have not completed their migration.

  have a close el ([example][1]) but our
  function expected `getCloseEl` to exist.
- This MR fixes a bug that'll prevent a lot of
  JavaScript from working since we try to
  set up flashes in our critical application path
  ([see comment][2]).

Fix the Create new cluster feature

See merge request gitlab-org/gitlab!62341

Basic authentication was removed for GKE cluster versions 1.19
Our API call to create GKE clusters did not specify a cluster version,
thus the integration started breaking as soon as Google defined that
1.19 is the default version.

The quickest solution is to pin the k8s version to 1.18.
