stats: Revert the previous OpenMetrics info type revert

The OpenMetrics standard does support "info" type. The original Prometheus
format doesn't support it, but our support is for OpenMetrics. They don't
even have any overlapping types that could be used for this, so the only
other possibility would have been to make this configurable.
