This change adds a new 'datasource' parameter to the dashboard metadata.
This way, the Grafana client state will manage only the dashboards that
match with the deployed datasource (either InfluxDB or Prometheus). For
backward compatibility, the client will always manage the dashboards
that don't set this new parameter.

This patch adds a default panel that will be used when another service
will add a new panel into the main dashboard through grains. This is the
common part between all panels of the main dashboard.
It replaces the static main dashboard that has been removed.
This patch separates the configuration of Grafana client. This allows to
configure the client, restart the minion to read the conf and finally
apply the grafana.client state.
