Put all actions into one single command

[ljvmiranda921]

Instead of just running the following steps:

cloud-build-badge \
    --id myFunction \
    --repository my-repository \
    --branches master development \ # You can supply multiple values
    --bucket my-project-bucket

and

gcloud functions deploy <ID> \
    --runtime nodejs6 \
    --trigger-resource cloud-builds \
    --trigger-event google.pubsub.topic.publish

separately, it would be much better to put them into one single command, ideally:

cloud-build-badge add repo

then it just gives you the generated link as a markdown file
