    Add skip_deploy_identifier

    Add a new action argument, skip_deploy_identifier to DeployStackAction.
    The argument will disable setting a unique value for the
    DeployIdentifier parameter, which means the SoftwareDeployment resources
    in the templates will only be triggered if there is an actual change to
    their configuration. This argument can be used to avoid always applying
    configuration, such as during node scale out.
