Issue #1040

This is my first PR here 😄

Summary

Originally, I was going to set a X-Nomad-Version on every request, then check the header on every request to any API, but I didn't think it was very clean and it would be a big changeset. I also thought it might get annoying for users to see the warning for several commands.

Instead, I just added the revision to nomad server members -detailed.
