The goal is to remove almost all references to the
golang.org/x/net/context package.
github.com/gogo/protobuf => v1.2.1
google.golang.org/grpc => v1.19.1
github.com/grpc-ecosystem/grpc-gateway => v1.18.5
It also replaces github.com/cockroachdb/cmux by github.com/soheilhy/cmux
because of [1] which fixes#3909 incidentally.

* *: bump gRPC dependencies
This change updates the gRPC dependencies to more recent versions:
* github.com/gogo/protobuf => v1.2.0
* github.com/grpc-ecosystem/grpc-gateway => v1.6.3
* google.golang.org/grpc => v1.17.0
In addition scripts/genproto.sh leverages Go modules information instead of
hardcoding SHA1 commits. This ensures that the code is generated from
the exact same sources.

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The particular outdated packages in vendor are: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.
