Implementation proposal
- Custom Metrics base based on the New Metric System.
- Allow to register essential ready-to-use metrics like LongMetric which can be exported by a providing metric exporter.
- User can add own metrics into different registries.
- Custom metrics are separated from the internals by registry name prefix "custom." (lower cased).
- Names of custom metrics and their registries can't contain any spaces.
- Management of custom metrics might require a permission.
