fix(logger): use godep for dependencies

This issue was brought up when building a new release of images for
deployment. The logger relied on `go get` to fetch dependencies. Because
there was a breaking change in the etcd client[1], the logger failed to
connect to the cluster. We have moved over to a global Godeps for
managing dependencies, so this changes the compilation on the host to
follow the other components' build process.
