Refactor EE Documentation Homepage

Closes gitlab-ce#53124

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.

EE: Validate that foreign keys are created

Closes gitlab-ce#50875

See merge request gitlab-org/gitlab-ee!8232

GitLab EE extends Member#add_user by adding some LDAP specific flags.
Prior to these changes, the only way this could be done was by modifying
Member#add_user in place. This could lead to merge conflicts whenever a
developer wants to change this method.

To resolve this issue, the logic that EE extends has been moved into a
separate method with the appropriate arguments. This allows EE to extend
the logic by prepending the method using an EE specific module.
