Fixes testing packages compatibility issues with grpc from 1.55.0 onwards
Resolves #15877

Note that 3.5 has huge difference from the main branch in terms of code structure, so usually it isn't recommended to cherry pick any commits from main.

@chaochn47 since you are the original author for bumping grpc in main branch, could you guide/work together the contributor to complete this PR?

Hey @rsafonseca sorry for the late reply.

This PR updates gRPC directly from v1.41.0 to v1.58.0 by cherry-picking #16338. It does not look correct because it missed quite a lot test updates when we upgraded from v1.41.0 to v1.52.0.

For example:

The following test failure of current PR was caused by unix://localhost:port was never officially supported. As part of the gRPC-go version update, we have to change to unix:localhost:port just like #14125.

logger.go:130: 2023-09-14T07:48:09.275Z	ERROR	default	grpc gateway failed to dial	{"addr": "unix://localhost:41618", "error": "failed to build resolver: invalid (non-empty) authority: localhost:41618"}

Please back port all gRPC updates and associated tests since main and release-3.5 diverged. I just blamed the change history of root go.mod.

The history from v1.41.0 to v1.58.0 is

• Update to grpc-1.47 (and fix the connection-string format) #14125
• bump grpc to v1.51.0 from v1.47.0 #14834
• Fix http2 authority header in multiple endpoints scenario and bump up grpc from v1.51.0 to v1.52.0 #16324
• Fix 15877 and bump up gRPC from v1.52.0 to v1.57.0 #16338

I would recommend you back port them one by one in ascending order and check if the local test passes or not by following the contributing guide. Let me know when the first PR is out.

I will help you complete this and eventually fix #15877. If you prefer DM, I have sent you the invitation to join the kubernetes slack workplace and I am in the #etcd channel.

In order to use Outlier Detection, release-3.5 should be at least gRPC-go v1.50.0 onward. Working on it..

Discussed during etcd triage. I can take a look to confirm this changes are already satisfied with a different PR.

/assign @moficodes Thank you very much Mofi!

[rsafonseca]

I can confirm that they are! This was handled in another thread, we can close it :)
