Fixes #600
This PR adds some guidelines for interoperating with OpenMetrics systems.
I have not fully specified the behavior of accepting OpenMetrics metrics -- I've delegated that to the existing design document in the collector's prometheus receiver. I am making the assumption that this is the only place we expect to accept OpenMetrics data into OpenTelemetry, and that their design document is sufficient for now.
I have included guidelines about metric and label renaming when converting OpenTelemetry metrics to OpenMetrics.
I have not included details about the values, or about how many OpenMetrics metrics should be created for each OpenTelemetry aggregation type. I'd love to chat more about the details here before it gets written up.
