Request streaming test sometimes fails: HTTP/2 stream not closed cleanly

[csvance]

I'm not sure if this is an issue with us overloading the test server or something on the client side, but it should be documented here.

Request Streaming: Error During Test at /Users/runner/work/gRPCClient.jl/gRPCClient.jl/test/runtests.jl:189
  Got exception outside of a @test
