Define if it is an error or not to receive for the same "Resource, InstrumentationLibrary, MetricName, Labels/Attributes, StartTime" first point with int value and next point with double value.

We need to document this behavior.

Copying from Slack to make sure it's not lost: OM considers it non-breaking, but not something that should happen frequently: https://github.com/OpenObservability/OpenMetrics/blob/main/specification/OpenMetrics.md#exposition-across-time-and-metric-evolution

We discussed this in the Metrics Data Model SiG.

  1. Based on previous discussion we don't think this is blocking declaring our API sstable.
  2. We should specify what is allowable within a collector ("on the wire"), specifically around aggregations.

We had talked about a notion of "weak conformance" that allows migrating int to double when this situation occurs. Specification remains TBD.
