This reverts commit d4d48591 but not
completly, just the parts needed for the services moved to ns4.

I'm moving some services to ns4, some will remain on host01. I'm
branching to have specific deployment for each host. So have a minimal
and generic master branch so common changes will be done there and I'll
rebase the other branches on top of it.

So the directory is always there (in case I'm going to delete the files
inside).

I really should have added those much earlier.

- Use common pre-commit snippet for Docker projects.
- Use GitLab CI template for pre-commit job.

In case the host isn't passed (or isn't known), redirect to
www.shore.co.il.

Now that I finished migrating all repos (FINALLY!!!).

No shell scripts to check.

It could lead to a case where the site is effectively offline.

Still, it will there in the image. That's fine with me.

- Replace file with configuration snippet.
- Allow some domains, disallow others.

We set it in the proxy anyway, don't send 2 Strict-Transport-Security
headers.
