support multiple relations per service

[jamesbeedy]

Currently it seems this interface only provides support for one host/port config per service.

It would be nice to be able to do something like

provides:
  http:
    interface: http
  https:
    interface: http

@when('http.available')
def configure_http(http):
    http.configure(80)

@when('https.available')
def configure_https(https):
    https.configure(443)

This is totally a bunch, likely with scope. We'll take a look tomorrow 👍

Hello, Any updates on this issue ??
for one of my charm we require http and https ports. so if this issue gets resolved it would help my charm to use this interface.
