Add a check_telemetry method to javelin

Adds simple queries of the telemetry service that check that meter
data properly survives an upgrade.

JAVELIN_START is recorded to provide a way to confirm that the
oldest available data is from before the upgrade, thus confirming
that the data survived the upgrade.

Partially implements: blueprint grenade-resource-survivability
