Docker compose support

Thanks for your pull request, we really appreciate contributions!

Please understand that it may take some time to be reviewed.

Also, make sure to follow the Contribution Guide.

Define the container setup in task yaml file like:

container:
  # Definition needs to be a valid docker-compose definition
  context: default
  definition:
    services:
      container:
        image: ubuntu:latest
        volumes:
          - ./containers/local/config:/local/config:delegated
        environment:
          - FOO:BAR
        command: sleep infinity
        init: true

Either force the task to run in a container by setting the param force_container to true on the task or using the cli arg --force-container

The thought process here is when running locally a container may be optional but might be required when used in a CICD pipeline.

As I also said on #974 (comment), Iḿ closing this on favor of #448.

@andreynering thanks for taking a look, the concept in #448 looks great.
