Use case: To help us with things like this project-isizwe/wifi-chat#16 (comment)

Affiliation retrieval

Filters affiliations list to those with 'member' affiliation:

<iq type='get'
    from='[email protected]/elsinore'
    to='pubsub.shakespeare.lit'
    id='ent1'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub' xmlns:bc='http://buddycloud.org/v1'>
    <affiliations node='princely_musings' bc:affiliation='member' />
  </pubsub>
</iq>

Subscription retrieval

<iq type='get'
    from='[email protected]/barracks'
    to='pubsub.shakespeare.lit'
    id='subscriptions1'>
  <pubsub xmlns='http://jabber.org/protocol/pubsub' xmlns:bc='http://buddycloud.org/v1'>
    <subscriptions bc:subscription='subscribed' />
  </pubsub>
</iq>

Rules

Only moderators and owners can retrieve outcast or none. Only users with a status of subscribed can retrieve data*.

• Only if this matches current functionality otherwise to match current.

Any thoughts on how we could page results? Use case: asking for subscriptions of all-users-auto-subscribed-channel@domain.

It just needs someone to implement RSM for subscription/affiliation
gathering again. It was taken out so we could switch to node memberships
more easily but there's no big reason we can't add it back in again.

I'm also thinking we should implement a 'memberships' stanza which is a
combo of subscription and affiliation.

A membership stanza would make a lot of sense.
