List of OTEL processors https:/open-telemetry/opentelemetry-collector/tree/master/processor

Based on #2148 (comment). OTEL collector might run without any processor.

Use of the queued_retry processor may be required if we want a certain set of metrics - I will re-review the metrics again this week following some changes upstream, so we can list which metrics would be dependent upon which particular processors.

Once our storage exporters will accept batches we could enable batch and queued retry processors.

For now, I wanted to enable memory limiter, however, it accepts absolute settings. I have submitted a proposal to accept percentage configuration open-telemetry/opentelemetry-collector#1078 that would enable us to enable it by default for any deployment.

Closing as it is a "low level" issue related to V2 which might take a different approach.
