Add the function f as a gauge with the given name.
The returned gauge value is only weakly referenced by the StatsReceiver, and if garbage collected will eventually cease to be a part of this measurement: thus, it needs to be retained by the caller. Or put another way, the measurement is only guaranteed to exist as long as there exists a strong reference to the returned gauge and typically should be stored in a member variable.
Measurements under the same name are added together.

Prepend namespace and namespaces to the names of the returned StatsReceiver.
Prepend namespace and namespaces to the names of the returned StatsReceiver.
For example:
```
statsReceiver.scope("client", "backend", "pool").counter("adds")
```
will generate a counter named /client/backend/pool/adds.
Note it's recommended to be mindful with usage of the scope method as it's almost always more efficient to pass a full metric name directly to a constructing method.
Put this way, whenever possible prefer
```
statsReceiver.counter("client", "backend", "pool", "adds")
```
to
```
statsReceiver.scope("client", "backend", "pool").counter("adds")
