Funnily enough, my initial implementation did include endpoint data in
RelationStatus but I removed it because the data was mostly repeating
what was already in the relation name. I'm happy to put this back in
though.
Looking at the AddRelation API, it returns a map[string]
where the key is the service name. I'm not sure that it makes sense for
RelationStatus to represent endpoints in a map - a slice probably makes
more sense.
How about each RelationStatus holds a slice of EndpointStatus structs
which have a subset of what AddRelation returns? The EndpointStatus
fields would be something like:
ServiceName string
Interface string
Role charm.RelationRole (string)
How does that sound?

I haven't been making a distinction - these changes currently let the
StatusData-
should to ensure that internal-only data doesn't leak out. I don't see
many places in the code that currently make use of StatusData. I'll
whitelist the allowed keys or something.
