Metrics v3 is mainly a reorganization of metrics into smaller groups of metrics and the removal of internal aggregation of metrics received from peer nodes in a MinIO cluster. This change adds the endpoint `/minio/metrics/v3` as the top-level metrics endpoint and under this, various sub-endpoints are implemented. These are currently documented in `docs/metrics/v3.md` The handler will serve metrics at any path `/minio/metrics/v3/PATH`, as follows: when PATH is a sub-endpoint listed above => serves the group of metrics under that path; or when PATH is a (non-empty) parent directory of the sub-endpoints listed above => serves metrics from each child sub-endpoint of PATH. otherwise, returns a no resource found error All available metrics are listed in the `docs/metrics/v3.md`. More will be added subsequently.
