Bartek Plotka c3434a39b7 proto: Allow reproducible proto generation.
Current way of setting prometheus project to generate repo is tedious.
If you just go install packages described in README.md
it ends up with those (non buildable code)
```
../../../prompb/remote.pb.go:61:34: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo
../../../prompb/remote.pb.go:109:33: undefined: "github.com/prometheus/prometheus/vendor/github.com/gogo/protobuf/proto".InternalMessageInfo

The issue is that the guide presented in proto folder is asking to
install some GO packages. It does not mention from what version and
there is strong mismatch between those used to generate proto and those
that are vendored and used to run the code later...
The particular outdated packages in vendor are:
`github.com/gogo/protobuf` and `google.golang.org/grpc`.

Just updating vendor would be not enough, as it would only tmp fix.
I propose adding script that will parse version from vendor.json and install correct version.

Changes:
- Added script that uses packages in *exactly* the same version the Go code is build against later.
- Regenerated proto with those pinned deps.
- Updated REAMDE.md
- Added `make proto`Current way of setting prometheus project to generate code from proto files is tedious.
