Feature request: statsd and prometheus receivers

[njLT]

The statsd and prometheus receivers are available in the opentelemetry-collector-contrib repository. We're currently using the legacy agent for statsd integration on GCP and were currently looking for a way to get some other metrics exposed in the prometheus format to stackdriver as well.
