This is a new transformation type that allows to describe a change where a metric is converted to several other metrics by eliminating an attribute. An example of such change that happened recently is this: https://github.com/open-telemetry/opentelemetry-specification/pull/2617 This PR implements specification change https://github.com/open-telemetry/opentelemetry-specification/pull/2653 This PR creates package v1.1 for the new functionality. The old package v1.0 remains unchanged.
