Will leave this in draft until the testbed refactoring is complete. |

This PR has been updated to use a new, separate copy of Lightstep's OTel exponential histogram mapping functions and data structure. Please take another look! |

There was a problem hiding this comment.
LGTM, my only pending question is #12951 (comment) (also one small thing missing from the v0.62.0 bump).
I will merge after you reply @jmacd if @codeboten has no further comments

Description:
Adds a "histogram" option to enable the OTLP v0.11 auto-scaling exponential histogram aggregator for Timing and Histogram measurements.
This uses the Histogram mapping functions and data structure implemented in github.com/lightstep/go-expohisto.
The same mapping functions and data structure are pending as for OTel-Go (e.g., open-telemetry/opentelemetry-go#3022); if OTel-Go agrees to expose these APIs, this module can be updated to use it directly, see:
open-telemetry/opentelemetry-go#3169
open-telemetry/opentelemetry-go#3170
Link to tracking Issue:
Fixes #5742
Testing: New tests added.
Documentation: README.md updated with examples including histogram configuration.
