This PR attempts to store the most recent config md5 checksum, and when it happens as metrics to catch any inconsistencies between current and desired state. The same strategy is used by prometheus/alertmanager#coodinator.

Changes

  • Exposes 3 new metrics: thanos_receive_config_hash, thanos_receive_config_last_reload_successful and thanos_receive_config_last_reload_success_timestamp_seconds.

Verification

make test, make lint, make build and manual verification of the metrics.
