The current documentation suggests that a user can not use his own
runner for a specific group or project. At first I thought this was the
case but it is not true, since we do allow websocket connections on
GitLab.com, this was discovered as part of the investigation on
https://gitlab.com/gitlab-org/gitlab-ce/issues/52611.
In the administration page for web terminals add a new `Security`
section explaining how the interactive web terminals are secured between
GitLab and gitlab-runner.
This section is under administration instead of
`doc/ci/interactive_web_terminal` because the administrators of the
GitLab instance would be mostly interested in this, whilst
`doc/ci/interactive_web_terminal` are interested in how the feature
works.
