kubectl multi-version brews

Applicability

The instructions below apply to older versions of Homebrew which still provide switch capability.

For current Homebrew, you'll likely need to keep Versions around, and build locally. Here's my versions repository https://github.com/rdump/homebrew-versions

MacPorts is now keeping versioned installations available as well, by default.
