[Juju] Multiple sub service with a relation

[Samuel Cozannet]

Thanks John!

Allow me to rephrase as I am not sure I am following. Are saying we could
have a declarative format in the configuration of the charm that would
apply to relations created like:

"datasources" : [
  { "name": "mysql",
    "datasets": [ "ds1", "ds2", ... ],
  },
  { "name": "mongodb",
    "datasets": [ "ds3", "ds4", ... ],
  },
  ...
  ]

and then config-changed hook would replay the creation of relations for any
new datasets?

@Alberto, Ana: if my understanding is correct, this would be a way to
expose the configuration of the datasets / schemas from the charm config.
Some code to generate to manage errors (absence of dataset, absence of
relation to datasource, wrong datasource definition...) but it seems closer
to Juju's philosophy than using actions.
