(https://github.com/open-telemetry/opentelemetry-
python/pull/3913))
* Fix prometheus metric name and unit conversion (#3924) -
this is a breaking change to prometheus metric names so they
comply with the specification. - you can temporarily opt-out
of the unit normalization by setting the environment variable
`OTEL_PYTHON_EXPERIMENTAL_DISABLE_PROMETHEUS_UNIT_NORMALIZATI
ON=true` - common unit abbreviations are converted to
Prometheus conventions (`s` -> `seconds`), following the
collector's implementation - repeated `_` are replaced with
a single `_` - unit annotations (enclosed in curly braces
like `{requests}`) are stripped away - units with slash are
converted e.g. `m/s` -> `meters_per_second`. - The
exporter's API is not changed
* Add parameters for Distros and configurators to configure
