grafana_system_user and grafana_system_group are not used

[IyadKandalaft]

What happened?

The grafana-server service fails to start. Upon review of the logs, I noted that it fails to create the logs directory because of denied permissions. When I look at the process owner and group, it's grafana for both, which is not what I set grafana_system_user and grafana_system_group to. Upon review of the repository, the variables are not referenced anywhere.

Did you expect to see some different?

Yes, the server process should have the correct ownership as defined by the variables.

How to reproduce it (as minimally and precisely as possible):

Set grafana_system_user and grafana_system_group to something other than the default. Look at grafana-server service to see that the user has not changed.

You're right, this is a documentation bug as those variables should be deleted from readme. This role is installing deb/rpm package offered by grafana organization and as such cannot influence settings inside said package (like system user or group setting).
