I'm pretty sure yields always compile into an allocating structure.

Looks like MetricProcessor is not used anymore. Is the plan to remove in a follow up?

Do we want this to be a method or a get property?

Trying the to-be-merged spec for MetricReader : https://github.com/open-telemetry/opentelemetry-specification/pull/1888/files
Note that we don't support multiple MetricReaders currently, this will be added in follow ups.
Replace Batch with plan IEnumerable as per discussion in Refactor aggregator and exporters #2295 (comment)
Modified Console/Prometheus (To demonstrate one push and one pull based). Rest of the Exporters, and clean up of existing MetricProcessor,Push/PullProcessor will be follow up PR to avoid making this PR even bigger. (Same for proper implementation/lack of it for Flush/Shutdown etc)
Addressed this comment: Refactor MeterProvider to be similar to TracerProvider #2141 (comment)
