This is a bit complicated and entangled, sorry.
First, we squash the auth-based smoke tests into the regular smoke
tests; we just run all the tests with auth on and that way we don't
need to spin up an entire separate cluster of machines just to run
a single query against them.
We improve the error detection, and standardize the jq-to-get-config
code. The purpose of this is to try to make sure that, if we actually
hit a failure and get "null" for a host name, we report *that*
as an error, rather than running ahead and producing 20+ separate
reports that ssh failed because it couldn't find a host named null.
