Use a "local" command for configuring Grafana

Currently the grafana-configure.sh script is executed in
a job. So if the Grafana Pod is re-created all the
pre-configured Grafana dashboards are lost. This commit
fixes the bug by using a "local" post command instead of
a "single" post command for the execution of
grafana-configure.sh.
