Resolvers in Traefik 101

[aarontees]

First of all, thank you for your Traefiki 101 guide—it got me up and running after a lot of searching. However, I ran into one hiccup, and that was not specifying the resolvers here like you do in your infra repo. Once I included them I was up and running, so maybe they should be included in your bare minimum setup. Thanks again, love all you do!
