stack setup --upgrade-cabal doesn't work for Cabal-2.2.0.1 + ghc-8.2.2

[mgsloan]

Steps to reproduce

stack --resolver lts-11.11 setup --upgrade-cabal

Expected

Upgrades cabal version (I have Cabal-2.0.1.0 installed, but this attempts to install Cabal-2.2.0.1)

Actual

Side note: I found the message "Manipulating the global Cabal is only for debugging purposes" to be surprising. I find the phrasing to be quite humorous, but this does not match with my understanding of --upgrade-cabal. It was added in 90ae9ec#diff-4968f87e674615592e572f2ec593e5b0R636

Method of installation

Installed via stack install in latest git repo.

My recommendation: this feature is already basically deprecated with:

Manipulating the global Cabal is only for debugging purposes

Let's officially deprecate it, and have it print a big warning message when used with GHC 8.2 or later.
