backend, frontend: prepare remote control: This is a series of changes necessary to prepare the implementation of remote control feature: - XEP-0166: add a `priority` attribute to `ApplicationData`: this is needed when several applications are working in a same session, to know which one must be handled first. Will be used to make Remote Control have precedence over Call content. - XEP-0166: `_call_plugins` is now async and is not used with `DeferredList` anymore: the benefit to have methods called in parallels is very low, and it cause a lot of trouble as we can't predict order. Methods are now called sequentially so workflow can be predicted. - XEP-0167: fix `senders` XMPP attribute <=> SDP mapping - XEP-0234: preflight acceptance key is now `pre-accepted` instead of `file-accepted`, so the same key can be used with other jingle applications. - XEP-0167, XEP-0343: move some method to XEP-0167 - XEP-0353: use new `priority` feature to call preflight methods of applications according to it. - frontend (webrtc): refactor the sources/sink handling with a more flexible mechanism based on Pydantic models. It is now possible to have has many Data Channel as necessary, to have them in addition to A/V streams, to specify manually GStreamer sources and sinks, etc. - frontend (webrtc): rework of the pipeline to reduce latency. - frontend: new `portal_desktop` method. Screenshare portal handling has been moved there, and RemoteDesktop portal has been added. - frontend (webrtc): fix `extract_ufrag_pwd` method. rel 436

pubsub/node/affiliations: nodes affiliations management
=======================================================

``affiliations`` is a subcommand handling the affiliations of a node (not to be confused
with ``pubsub affiliations`` which handle the affiliations of a PubSub service).

get
===

Retrieve entities affiliated to this node and their role.

example
-------

Get affiliations of a node::

  $ li pubsub node affiliations get -n some_node

set
===

Set affiliation of an entity on a node. Affiliations are specified with ``-a JID
AFFILIATION`` argument. Check `XEP-0060 affiliations`_ for allowed values for
``AFFILIATION``. Use ``none`` to remove an affiliation.

.. _XEP-0060 affiliations: https://xmpp.org/extensions/xep-0060.html#affiliations

example
-------

If we have a whitelisted node ``some_whitelisted_node``, we can allow
``louise@example.net`` to publish on it (by setting her role as ``publisher``), and
``pierre@example.net`` to access it (by setting his role as ``member``) using the
following command::

  $ li pubsub node affiliations set -n some_whitelisted_node -a louise@example.net
  publisher -a pierre@example.net member
