Repo2docker-action: Repo2Docker Example Brainstorming

I plan on fleshing out the docs in this repo a bit more to add relevant examples that illustrate practical use cases for using repo2docker

1. Have Actions comment with a Binder badge automatically on a PR, or with a chatops command that corresponds to the branch referenced in the PR. This is so reviewers can get easy access to a live notebook to review notebooks in the PR with just a click. Will look something like this:

   

2. Automatically launch notebooks when a PR is opened or with a chatops command on paperspace gradient.

   A rough sketch is something like this

   ...
     - name: build-environment
       id: repo2docker
       uses: machine-learning-apps/repo2docker-action
       with:
           DOCKER_USERNAME: ${{ secrets.DOCKER_USERNAME }}
           DOCKER_PASSWORD: ${{ secrets.DOCKER_PASSWORD }}
           IMAGE_NAME: "hamelsmu/repo2docker-test"
   
     - name: paperspace-deploy
       id: paperspace
       run: |
           pip install gradient
           gradient apiKey ${PAPERSPACE_TOKEN}
           gradient jobs create --container ${IMAGE_NAME} --projectId ${PAPERSPACE_PROJECT_ID} --machineType K80 --ports 8888:8888
       env:
           PAPERSPACE_TOKEN: ${{ secrets.PAPERSPACE_TOKEN }}
           PAPERSPACE_PROJECT_ID: ${{ secrets.PAPERSPACE_PROJECT_ID }}
           IMAGE_NAME: ${{ steps.repo2docker.outputs.IMAGE_SHA_NAME }}
   
   

3. Launch repo2docker images on the major clouds: GCP, AWS, Azure and maybe FloydHub

   A rough sketch looks like this on GCP - Google Cloud Functions

   ....
     - uses: exelban/gcloud@master
       env:
           PROJECT_ID: ${{ secrets.GOOGLE_PROJECT_ID }}
           APPLICATION_CREDENTIALS: ${{ secrets.GOOGLE_APPLICATION_CREDENTIALS }}
           IMAGE_NAME: ${{ steps.repo2docker.outputs.IMAGE_SHA_NAME }}
       with:
           args: --quiet beta run deploy notebook-serve-action --allow-unauthenticated --platform managed --region us-west1 --image $IMAGE_NAME
   

4. Examples with codespaces

Other Ideas: TBD

@betatim, @willingc @neovintage any other ideas? The possibilities are so exciting, would love your ideas and thoughts!
