Enclosing interface:

InternalBridge
```
public static interface InternalBridge.MetricRegistry
```
Abstraction of the MetricRegistry behavior used by internal Helidon clients.
The exposed methods use version-neutral abstractions for Metadata, MetricID, and Tag which are used by MicroProfile Metrics. Some methods have bridge in their names because the corresponding MicroProfile Metrics methods changed return type but kept the same signature from 1.1 to 2.0, so here they need distinct names to distinguish them from the spec-prescribed methods (that do not use the version-neutral constructs).
