I started work on a Waypoint builder plugin for dobi

[Fuco1]

Hey @dnephin!

Just an FYI, I started a project https://github.com/Fuco1/waypoint-plugin-dobi to make a builder plugin for HashiCorp Waypoint utilizing dobi to build docker images.

It's a very early stage project and I'm a go noob, but I plan to hack on it to learn and do something useful. Just letting you and the community know so we don't duplicate the efforts.

So far it can build a single image by using the dobi.yaml (basically just shells out). It's basically a very thin wrapper around just calling dobi directly, but provides the ease of use and consistent environment for Waypoint users.

Cheers!
