    add vendor_data to the md service and config drive

    There was not previously any way for a vendor to extend the metadata
    service to include vendor specific or site specific information.

    This adds an entry named 'vendor_data.json' to the metadata service, and also
    to the rendering on config-drive. vendor_data is intended to be a un-managed
    place for cloud providers to put custom data that will then be available to the
    instances.

    The class used to generate the data is configurable via the flag
    'vendordata_driver'. The default class, JsonFileVendorData simply
    loads data from a file that is configurable via 'vendordata_jsonfile_path'.
    If that variable is not set, a empty dictionary is returned.

    By setting
     vendordata_jsonfile_path = /etc/nova/vendor_data.json

    The cloud provider can then expose custom data to all instances.

[Nermina Miller (nerminamiller)]

Tom, does this section need to be updated to reflect this metadata change: http://docs.openstack.org/trunk/config-reference/content/configuring-multiple-compute-nodes.html?

By the way, this table has a duplicate entry: http://docs.openstack.org/trunk/config-reference/content/networking-options-metadata.html.
