It seems that pbr's "warnerrors" isn't actually doing anything at the
moment (I680b448471e687919d202e8f2abe57f8ba3b22ee) meaning we're able
to commit docs with RST parser errors. Fix all these up in some
minimal way (I have not audited content, just made it pass build).
Link the specs in so they're referenced from the top level.

Evidently the readme file hasn't been updated since rhel7 finished
beta, so this is long overdue.
In addition, since it's not possible to download the base image
file directly, let's stop pretending we can and bail out if the user
didn't set the necessary env vars.
Also updated the README to use the new table format instead of free text
