杨金珏 6220174687 support custom grpc.MaxConcurrentStreams
There is no update on the original PR (see below) for more then 2
weeks. So Benjamin(@ahrtr) continues to work on the PR. The first
step is to rebase the PR, because there are lots of conflicts with
the main branch.

The change to go.mod and go.sum reverted, because they are not needed.
The e2e test cases are also reverted, because they are not correct.
