gRPC client generated python files are really old

[omidb]

Is your feature request related to a problem? Please describe.
This is a blocking issue for us.
gRPC-generated files are old and incompatible with many other libraries (tested for Python). As has been mentioned here:

Restrict maximum version due to breaking protobuf 4.21.0 changes
(see protocolbuffers/protobuf#10051)
TODO: Update to be compatible with 4.0 release (DLIS-3809)
protobuf>=3.5.0,<3.20
There is memory leak in later Python GRPC (1.43.0 to be specific),
use known working version until the memory leak is resolved in the future
(see grpc/grpc#28513)
grpcio==1.41.0
numpy>=1.19.1
python-rapidjson>=0.9.1

Describe the solution you'd like
We can do two things: Release the client with two different Protoc support: version 3 and version 4. Or we can just increase the version to the latest.

Describe alternatives you've considered
Using HTTP or gRPC but not using the triton-client package which is not ideal as there are many nice optimizations in the package.

Hi @omidb, we have a ticket to increase the protobuf version. I have added your request into the ticket.

@kthui thanks

I was accidentally reporting to old PR regarding this issue.

triton-inference-server/client#109 (comment)

@kthui can you tell why this cannot be implemented straight away?

perf_analyzer is not part of a tritonclient library, thus this requirement is unnecessary.

This dependency requirement should be resolved by restricting version in docker image wich includes perf_analyzer.

This is also a blocking issue for us, and the supported Python version is 3.8, which is very old right now.
