Toshio/Product Divergence (config)

We want to have products be able to specify divergent and conflicting behaviour.

Use cases

(at least sgallagh and abadger1999 :-)

install time -- we want the product you're installing to determine which configuration you get.
installing a package on an existing system -- if it has separate config, we'd like the package manager to choose the configuration for the product you're using.
Want to have a single tool that can switch default configs per-package. Which things you can switch may depend on what combinations we support and how the user has selected which Products are "active" on their system.
1. Tool should not switch out user-modified configs unless run with --force

Product union: Installed Cloud or Server but want a graphical environment. Preference is to make that be Workstation. (We want it to be as close to Workstation as possible, to benefit from existing testing)
1. recommendation implementation: the defaults should not change for anything that was part of the installed Product, but new packages should get the Workstation default
Product conversion: Installed Cloud or Server but want a graphical environment. Convert existing config to workstation and install additional packages on top to get a Graphical environment.
