Remove the maximum version pinning of protobuf and grpc in the future #1095
Description
In issue 1092, we documented how the protobuf version can lead to a potential broken client library.
In issue 1086, it was brought to our attention that the GRPC C dependency was broken.
In v30.0.0, we fixed both issues, by pinning the protobuf and GRPC (C-extension) to an earlier version.
For any users still on v29.0.0, you should upgrade to v30.0.0 AND do a clean dependency installation to ensure the new protobuf and GRPC versions are picked up.
This feature request is to remove the pin to the GRPC extension when the underlying issue is fixed, as well as to remove the pin to protobuf (and update GetLabel to IsRequired) in the near future once we resolve the underlying dependency conflict.
