    Enable flavors metadata update

    Nova currently expose an api to let the users update
    the flavors metadata so horizon should expose
    this functionality. At the same time Glance is exposing
    a metadata dictionary in Juno, where users can register
    the key/value pairs that describe their cloud deployment.
    This patch uses the glance metadata api to expose the available
    metadata and the nova api to update the aggregates metadata.
