This chang creates a GaugeInfo metrics type for registering informational (textual) metrics, e.g. geth version number. It also improves the testing for backend-exporters, and uses a shared subpackage in 'internal' to provide sample datasets and ordered registry. Implements #21783 --------- Co-authored-by: Martin Holst Swende <martin@swende.se>
