I moved this work into the OTel-Go repo because it was difficult to develop an end-to-end demonstration. We need support for a new aggregator type and a new OTLP export code path; I may have to move it back to this repo, in which case I'll re-open this PR. |

This implementation of the OTLP v0.11 exponential histogram provides an aggregator for calculating ExponentialHistogramDataPoint values from individual measurements. The only configurable parameter of this implementation presently is the maximum size: it implements auto-scaling to fit all observed values into the available buckets.
This behavior will not work for all consumers, thus more development will be needed.
