Doug Szumski 2c730590d7 Improve Grafana DB bootstrap
This fixes an issue where multiple Grafana instances would race
to bootstrap the Grafana DB. The following changes are made:

- Only start additional Grafana instances after the DB has been
  configured.

- During upgrade, don't allow old instances to run with an
  upgraded DB schema.
