nixos/taskserver/helper: Implement deletion

Now we finally can delete organisations, groups and users along with
certificate revocation. The new subtests now make sure that the client
certificate is also revoked (both when removing the whole organisation
and just a single user).

If we use the imperative way to add and delete users, we have to restart
the Taskserver in order for the CRL to be effective.

However, by using the declarative configuration we now get this for
free, because removing a user will also restart the service and thus its
client certificate will end up in the CRL.
