[Datadog] Exporter configuration is incorrect

[DazWilkin]

exporters:
    datadog:
        namespace: ocagent
        enable_metrics: true
        enable_tracing: false

So:

• metrics enabled
• trace disabled

But, when I run the agent:

./ocagent_linux 
{"level":"info","ts":1551468810.0261667,"caller":"config/config.go:495","msg":"Trace Exporter enabled","exporter":"datadog"}
2019/03/01 11:33:31 Running OpenCensus Trace and Metrics receivers as a gRPC service at "127.0.0.1:55678"
2019/03/01 11:33:31 Running zPages at ":55679"

I'm unsure how to enable metrics.

I have the Datadog statsd agent running on :8125 but it does not appear to receive metrics through the agent using the sample code.

Metrics is not supported in the DD exporter today: https://github.com/census-instrumentation/opencensus-service/blob/master/exporter/datadogexporter/datadog.go

Well, that explains that then ;-)

It would be helpful to log an error if the user attempts to enable_metrics?
