When editing the modsecurity integration out, I didn't use sops, as a
result there was a mac mismatch which broke stuff. This patch fixes the
whole file

It seems I missed some client mapper. This patch should resolve it and
put the users into the right role.

This patch adds some external links to the docs navigation section.
Since mdbooks doesn't support this by default, this adds a JS file as
workaround, which avoids forking the theme or writing an extension for
mdbooks.

This patch changes the repository icon to GitLab as the repository isn't
set up on GitHub, the icon would be completely misleading.

This patch adds a title to the documentation as well as some links to
the repository as well as the WebIDE for GitLab adjustments.

Currently terraform isn't used, so it shouldn't be part of the README.

This patch adds the initial structure for the documentation of the
Shivering-Isles GitOps Infrastructure repository. It uses mdbook to
create an easy to read documentation.

It uses mdbook, because it's an easy single-binary tool to generate
documentation. This fits the tooling schema of koolbox quite well and
can be easily integrated into the automatic updates toolchain already
used. Further it uses markdown, which allows easy writing of further
documentation and re-use of existing documentation.

The documentation structure re-uses various existing READMEs from
components. These might be replaced in the long run.

It also lays out future plans for documentation, which is currently
still on the TODO list. This should help to keep the overall structure
in mind and provide the general direction.

The login works now, however the role-mapping seems to be flawed and
therefore broken, which results in everyone becoming just a viewer. This
patch reworks the role path to (hopefully) work as expected and use the
client-role assignment

This patch adds the root_url config, in order to generate the correct
redirect URL.

The grafana.ini variable isn't just a plain ini file, but a structured
document that is then translated to ini. I hope this works now as
expected.

This patch introduces some config variables that should result in
grafana no longer asking for the admin password but use oauth to
authenticate automatically.
