Lars Kellogg-Stedman 6116e4cdab docker: permit empty or false pid
The `docker` Python module only accepts `None` or `'host'` as arguments.
This makes it difficult to conditionally set the `pid` attribute using
standard Ansible syntax.

This change converts any value that evaluates as boolean `False` to
`None`, which includes empty strings:

    pid:

As well as an explicit `false`:

    pid: false

This permits the following to work as intended:

    - hosts: localhost
      tasks:
      - name: starting container
        docker:
          docker_api_version: 1.18
          image: larsks/mini-httpd
          name: web
          pid: "{{ container_pid|default('') }}"

If `container_pid` is set to `host` somewhere, this will create a
Docker container with `pid=host`; otherwise, this will create a
container with normal isolated pid namespace.
