>          Issue Type: Improvement
>    Affects Versions: 1.5.0
>            Reporter: Greg Mann

> When the {{force}} argument is not set to {{true}}, {{Docker::pull}} will always perform
a {{docker inspect}} call before it does a {{docker pull}}. If either of these two Docker
CLI calls hangs indefinitely, the Docker container will be stuck in the PULLING state. This
means that we make no further progress in the {{launch()}} call path, so the executor binary
is never executed, the {{Future}} associated with the {{launch()}} call is never failed or
satisfied, and {{wait()}} is never called on the container. Thus, when the executor registration
timeout elapses, the agent's call to {{containerizer->destroy()}} gets stuck waiting on
the container status, and its continuation is never invoked.
> This leaves the task destined for that Docker executor stuck in TASK_STAGING from the
framework's perspective, and attempts to kill the task will fail.
