    Exit 1 if a container fails and return the error

    When a container's volumes failed validation, paunch still exited 0.
    This caused the deployment to continue running even though not all
    containers had been started.

    This patch changes the rc to 1 when a container's volumes fail
    validation and the container can't be started. The error message is also
    returned in stderr so that it's available to the paunch ansible module
    and will be seen in the deployment output.
