go-bindata-assetsf missing from Hotrod example

[cory-klein]

Following the given hotrod instructions here.

When running this step:

cd examples/hotrod
go run ./main.go all

I get the following error message:

$ go run ./main.go all
services/frontend/bindata_assetfs.go:9:2: cannot find package "github.com/elazarl/go-bindata-assetfs" in any of:
	/Users/coryklein/go/src/github.com/jaegertracing/jaeger/vendor/github.com/elazarl/go-bindata-assetfs (vendor tree)
	/usr/local/Cellar/go/1.10/libexec/src/github.com/elazarl/go-bindata-assetfs (from $GOROOT)
	/Users/coryklein/go/src/github.com/elazarl/go-bindata-assetfs (from $GOPATH)

I was able to resolve with cd ../.. && go get ./..., but that wasn't mentioned in the documentation. Is the documentation wrong, or is there some configuration missing from the example itself?

run make build-examples. It will fetch bindata via go get

True is that we don't add bindata to glide. We should consider it.
