[gRPC-Python] grpcio-observability compatibiltiy with OTEL SDK 1.22.0+

[Kyle Strand]

The `grpcio-observability` requirements file (links below) specifies `opentelemetry-sdk == 1.21.0`. Is there a reason why this is pinned to a specific version, rather than using `^` or `>=`? The current OTEL PyPI release is 1.24.0. Additionally, is the OTEL SDK actually required, or could it use the API only, as `opentelemetry-api >= 1.21.0`?

If the version-pinning is necessary, can a version be released that supports OTEL SDK 1.22.0 or above?

Thanks!

Hi Kyle,

We actually do support versions higher than 1.21.0, we'll remove the version ping in the next release.

As for api vs sdk, we do need sdk to create MeterProvider in the example. But the observability package itself doesn't have a dependency on sdk as listed in setup.py (We'll also remove the version ping here).


Thanks,
Xuan
