EE: Improve variables support

See merge request gitlab-org/gitlab-ee!8483

Global features should be checked directly on the license
class `external_authorization` is one of these features.

This ensures that variables accept only string,
alongside also improves kubernetes_namespace,
improving validation and default value being set.

Revert "Merge branch 'docs/split-front-page-ee' into 'master'"

See merge request gitlab-org/gitlab-ee!8498

This adds support for smartcard authentication with basic X.509
certificates. NGINX needs to be setup in a way to run the same server
context on separate port requesting the client side certificate. Another
limitation is that the email address must be a part of the Common-Name
attribute.

This reverts merge request !7525

Refactor EE Documentation Homepage

See merge request gitlab-org/gitlab-ee!7525

Also:

- Add EE-specific links that were already in EE landing page.
- Add descriptions to links where none existed.

In EE, the DeployKeyController reloads the user's accesible key so that
it can audit changes. However, this has a side effect of preventing
admins from deleting keys in the interface.  Note that the deletion
problem does not happen in CE because auditing is not performed there.

We can clean up the code by reusing the key that was created or destroyed
and pushing the logic into the service.
