Fix dependency for grafana-configuration task
Fix dependency for grafana-configuration task

This change removes an unneeded dependency and it fixes a wrong one.
We don't need to wait that Grafana is configured before pushing data
to the backend, so we removed the dependency on upload_nodes_info.
And as the task grafana-configuration is only executed on the primary
role it depends on primary-grafana-installation.
