TEO11Y-60 Support For Datadog Distributions #139

Closed boggsboggs closed 2 years ago

boggsboggs commented 2 years ago

This PR makes two semantic changes:

Adds a FilteredHandler to the stats package that processes measures with a specified filter function before forwarding to another handler
Adds the UseDistributions flag to datadog.ClientConfig which sends all histogram measures as distributions

I did some refactoring in the datadog package to facilitate this change:

Converted datadog.AppendMeasureFiltered into a method on datadog.serializer named AppendMeasure
Moved datadog.serializer from datadog/client.go into datadog/measures.go
Renamed datadog/measures.go to datadog/serializer.go

Because of the mix of refactoring and code additions, I expect this PR will be easiest to review one commit at a time.
