Missing deployment_manifest alias

[Mulinho]

Automated deployment of app.yml with a correct deployment manifest taken from mcctl does not work. In the created App, deploymentmanifest field is empty. This can be easily fixed by changing this:

        for (key, alias) in (("access_ports", "accessports"),
                             ("default_flavor", "defaultflavor"),
                             ("image_path", "imagepath"),
                             ("image_type", "imagetype"):

into this:

        for (key, alias) in (("access_ports", "accessports"),
                             ("default_flavor", "defaultflavor"),
                             ("image_path", "imagepath"),
                             ("image_type", "imagetype"),
                             ("deployment_manifest", "deploymentmanifest")):

in deploy-app.py.
