Fixing error after regenerating protobuf code with latest version of protoc

[orenfromberg]

@kalilsn ran into a problem while trying to build the soapboxd image after regenerating the protobuf code with make protobufs. This branch updates a couple of dependencies and adds a small code change to regenerate the protobuf code and build the image.

After running make protobufs the *.pb.go files were regenerated successfully. Subsequently running make all causes the following errors to be exposed:

$ make all                                                                                                                                                                   ✔  10064  10:42:48

This problem seemed to be caused by a mismatch between the version of protoc being used and the revision of protobuf in the vendor directory. The Readme says to use the latest version of protoc, which in this case did not match the version in the vendor directory. To fix this I added a constraint to Gopkg.toml and ran dep ensure so that the revision of protobuf in the vendor directory is the same as the revision that the protoc executable originates from.

[[constraint]]
  name = "github.com/golang/protobuf"
  revision = "14aad3d5ea4c323bcd7a2137e735da24a76e814c"

Then running make all gave the following errors:

$ make all                                                                                                                                                               2 ↵  10068  10:51:46

This github comment suggested the problem was an older version of grpc, so I updated the grpc constraint accordingly:

[[constraint]]
  name = "google.golang.org/grpc"
-  version = "1.5.0"
+  version = "^1.13.0"

after running dep ensure and make protobufs, the make all error was:

make all                                                                                                                                                               2 ↵  10071  11:03:35

soapboxd/deployment.go:157:55: too few values in struct initializer
Makefile:13: recipe for target 'all' failed
make: *** [all] Error 2

so I changed this line:

-   envReq := pb.GetEnvironmentRequest{req.GetEnv().GetId()}
+   envReq := pb.GetEnvironmentRequest{Id: req.GetEnv().GetId()}

After that, make all completed successfully and the soapboxd image was built.
