Stabilize gRPC gateway (/v3beta)

[gyuho]

gRPC gateway serves /v3beta, should be ready as /v3

Reference #9064.

Not much to do here. Just trouble-shoot any issues that may come up. Or add any missing tests. And bump up endpoint to v3 before 3.4 release.

@hexfusion Do you want to work on this?

[hexfusion]

@gyuho I am a user of gRPC gateway and would love to see it stable /v3. Will try my best to support/improve.

[gyuho]

@hexfusion Thanks! Reference when bumping up to /v3 (#8880).

[xiang90]

the thing i worry about is that gRPC web is probably going to release soon. it can be the "official" way to expose gRPC service in JSON format.

[hexfusion]

@xiang90 does it make sense to make /v3 stable with grpc-gateway then look at grpc/grpc#8682 for /v4? Replacing seems a fair bit of work :).

[gyuho]

We will double-check with gRPC team.

[hexfusion]

I got the ball rolling here a little.

[xiang90]

@gyuho @hexfusion

this is the gRPC web issue: grpc/grpc#8682.

It is an official gRPC support instead of the one from improbable.

[hexfusion]

I see thanks.

[hexfusion]

@xiang90 @gyuho either of you getting early access per comments in issue?

[gyuho]

@hexfusion No, but seems like it should be out in a few weeks?

[hexfusion]

I asked for early access to get a feel for how this will look.

small snippet from readme re: grpc-web

The gateway that connects the client to the server uses Nginx. However, Nginx still doesn't support HTTP/2 (to backends) as of Q3/2017, and therefore the gateway can't be used as a reverse proxy (for load balancing). We have also added the gRPC-Web support to Envoy. In future, we expect gRPC-Web to be supported in language-specific Web frameworks too, such as Go, Java, Node, which will eliminate the need to deploy a gateway.

Being that it has a Nginx/Envoy dependency currently I do not see this becoming a short term alternative to grpc-gateway. A side car approach could be possible allowing maybe etcd-operator more reasonable support via Kubernetes. But still a ways off it seems for direct Go implimentation from gRPC team?

[xiang90]

OK. It seems like gRPC-web really only focuses on the Web part for web app builders rather than the ease of use as a JSON+HTTP API? If that is the case, let us move forward with grpc-gateway.

[gyuho]

@hexfusion @xiang90 Sounds good. People already depend on our current grpc-gateway anyway.

[hexfusion]

Understood grpc-gateway /v3 ahead!

[hexfusion]

Going to start on this tonight.

[hexfusion]

@gyuho @xiang90 do we want to support /v3beta and /v3 depreciating /v3alpha or only support /v3 for 3.4?
