Ruslan Aliev e99dfc1c84 Add run migrator job prior running grafana pods
During the first run, grafana will run migrator job, which populates
necessary fields in database. Previously, if there are two or more
grafana pods which start up simultaneously, it causes the race condition
for database access and finally one of the pods will fail (in some
cases both of them), leaving the grafana database in incomplete state.
