Add Cinc Branding File

As part of the chef/go-libs work that we performed was to allow go generate ./... was to allow us to overload the JSON file used by dist via a ENV variable.

This work creates a single JSON file that we can serve via our website for these builds.

DIST_FILE='https://cinc.sh/assets/cinc-branding-dist.json

The primary idea is to have singular place to store our builds, rather than spreading multiple repo and be attached to a commit via a permalink.
