If consul-client-go was not previously install build fails.

If I try to add it to glide.yaml:

 - package: github.com/edgexfoundry/consul-client-go

I got many [ERROR] Error looking for xxxxxxx: Cannot detect VCS, where xxxxxxx are different repositories, when I execute glide update

I tried to fix it in PR #23

Fixed in master
