Creates a new build of an application. Imports an <image> and deploys it to Drycc

Usage: drycc builds:create <image> [options]

Arguments:
  <image>
    A default fully-qualified container image, either from Drycc Registry (e.g. registry.drycc.cc/drycc/example-go:latest)
    or from an in-house registry (e.g. myregistry.example.com:5000/example-go:latest).
    This image must include the tag.

Options:
  -a --app=<app>
    The uniquely identifiable name for the application.
  -s --stack=<stack>
    The stack name for the application, defaults to container.
  -p --procfile=<procfile>
    A YAML file used to supply a Procfile to the application.
  -d --dryccfile=<dryccfile>
    A YAML file used to supply a drycc.yaml to the application.
  --confirm=yes
    To proceed, type "yes".
