Important remarks
The Grafana-Dogu contains an administrator user. This user is automatically a member of all created groups (teams)
and has full access to the dogu. It is not possible to log in with this user.
However, this user must not be deleted under any circumstances, as otherwise the Dogu will no longer work.
The account is necessary to synchronize groups.
The name of this user is partly randomly generated according to the following scheme: grafana_admin_<random characters>,
for example: grafana_admin_ubvwllxc13xu8cturincf3wfo7f6srtazo27k5lxokoitkic68.
