pack build

As a developer I want to use the pack buildcommand to create an image so that I can build my app using buildpacks, and run it similarly to how it will run in production

Acceptance Criteria

Given I have installed docker
Given Source code in a directory <app-dir>
When I run pack build --dir <app-dir> --name <repo-name>:<tag-name (optional)>
Then The pack cli builds an image from the source code in <app-dir> with the v3 buildpack lifecycle and puts it in <repo-name> in the local Docker daemon
Then I can run docker run ` and see my app running

Assumptions

1. For this first story we assume the image is fetched from and written to the docker daemon
2. We can skip restorer and cacher in this first iteration
3. We can assume the correct stack is packs/v3 on dockerhub

This is finished on develop branch. I am waiting on rebuilds of docker images to merge to master
