Fix the Glide dependency problem!

We’ve not been using Glide properly.

To date, we have pinned our dependent packages in the glide.yaml file, but not THEIR dependencies. Thios causes isues when you attempt to ensure you have all of the required versioned dependencies.

By adding not just our depndent pkgs, but THEIR dependencies to the Glide.yaml file, I was able to get the `glide up -u -s` command to run cleanly without updating any pkgs, just ensuring that the versioned packages specified in the glide.yaml and glide.lock files are the only ones being vendored.

This PR is based on the set of dependencies in our git repo today. So, once this PR gets merged, everyone should nuke their “vendor” folder within the portal=proxy and do a  `glide up -u -s` to ensure they are using the required dependent packages (and only those).

NOTE #1: There ARE four new packages included in this PR - those are unit testing related packages that have never been formally inclluded in our glide.yaml file, but should have been.

NOTE #2: Compare the glide.lock file here with one from the previoous commit on master branch - that will reflect how little this PR changes in terms of dependencies.
