Re-enable Erlang benchmark

[LesnyRumcajs]

Erlang benchmark stopped working (on my local machine all requests failed according to ghz report). Would be nice to identify the issue and resolve it. I temporarily disabled it to unblock CI.

Perhaps @fenollp , the local Erlang champion, you could take a look in spare time? :)

Ah indeed there is an issue with unary calls made from a Go client. I am tracking this here and will dig further once I find some time.

@fenollp thanks!

Yo, I'm the author of grpcbox and hope to help. I've not been doing much of anything recently though because I've been on paternity leave :), but want to get this figured out. I see I've already been ignoring an issue on the repo itself :(

Hi Tristan! Congrats :) and thanks for responding.

As you note there's this issue of the gPRC stream being unexpectedly reset during unary calls from a gRPC-go client.

If you can find some time to look into this that'd be very helpful :)

Closing this since the erlang benchmark works now.

I should have linked the PR to this issue.
FYI grpcbox (actually, chatterbox) still requires some patching. See the PR's dependency override.

Weird, I see I commented back when I was on my first paternity leave and now I've run into this again via a tweet during my second leave :).

Anyway, I saw our numbers are the worst, hehe. Recently had some major changes to the HTTP/2 client and server merged so hopefully that is going to change.

I haven't published the new versions to hex yet but opened up a PR to bump the benchmark #363
