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.

Implements: blueprint glaance-metadata-flavors
