    Retry previously failed deployments

    Previously, when the server pre and post deployments were run, if one
    failed, it would not be automatically retried since the deployed file
    for the deployment exists under /var/lib/heat-config/deployed.

    This could be overridden by passing -e force=true to ansible-playbook,
    however for deployments that have previously failed, I don't think this
    should be required, and we should just retry them automatically.

    This new behavior more closely matches the traditional behavior with
    Heat, where a stack update would automatically attempt to reapply and
    deployment that was in a failed state.
