    [Launch Instance Fix] Settings for volume name

    This patch provides the rest API needed to
    get settings that allow conditionally
    displaying the volume device name
    and admin password.

    Examples:

    settingsService.ifEnabled('setting').then(doThis);
    settingsService.ifEnabled('setting', 'expected', 'default').then(doThis, elseThis);

    Note: To test, you need to add the following to local_settings.py

    REST_API_REQUIRED_SETTINGS = ['OPENSTACK_HYPERVISOR_FEATURES']

    OPENSTACK_HYPERVISOR_FEATURES = {
        'can_set_mount_point': True
    }

    Change can_set_mount_point to False to see it not show up.
    Must restart the server.
