http scheme in service.swagger.json

[knweiss]

@philips I did take a closer look at your interesting grpc-gateway-examples code after reading the blog post and noticed some minor problems. I hope you don't mind if I open some issues even though this is "only" example code. Maybe other readers will find this useful.

The echopb/Makefile generates a service.swagger.json with

"schemes": [
    "http",
    "https"
  ],

I've added this line to the Makefile to remove the http scheme.

jq 'del(.schemes[] | select(. == "http"))' service.swagger.json >service.swagger.json.new && mv service.swagger.json.new service.swagger.json

Unfortunately, there's no protoc-gen-swagger option to do this directly.
See: grpc-ecosystem/grpc-gateway#161

And you can use this to set the version (used by the swagger-ui):

jq '.info.version = "0.0.1"' service.swagger.json >service.swagger.json.new && mv service.swagger.json.new service.swagger.json
