fixes #5260 (#5279)

Broken link, I presume this one was meant.

* Adds package that can configure using turnserver for jitsi-meet.

Activates http2 on the nginx host and uses the alpn send with the web requests to multiplex traffic to be served as web of proxied to the turn server.
It needs nginx at least v1.13.10.
Adds turncredentials module from Philipp Hancke, with small modification (all int values for hosts need to be strings/tostring()) in order to be able to use the module with prosody 0.11.

* Moves loading of stream after loading stream module (50-..).

* Leaves DISABLE_TCP_HARVESTER to be handled by jvb.

* Fixes comments.

* Properly detect first time coturn install and configure it.

* Handles upgrading from jetty serving web.

* Does not create jvb user if already exists.

* Fixes let's encrypt and adds turnserver handling.

* Enables use of turn server in config.js if available.

* Adds a check whether prosody config exists.

There are cases where deployments can still have configured prosody in the main prosody config in /etc/prosody.

Also adds a missing '/'.

* Adds an option to set email through iframe API init and to stats.

* Simplifies configuring email and displayName in stats.

Removes enableStatsID as not needed as when off we are sending as callstats id xmpp resource which is unique per call and id must be something that sticks between calls (callstatsUsername).

* Adds email and displayName in stats config for mobile.

* chore(deps): Updates lib-jitsi-meet to latest dd31f0a.

* Removes enableStatsID from config and whitelist.

* first pass at mod_muc_domain open source plus example

* doc - prosody config and config.js examples for mapper

Fixes: https://github.com/jitsi/jitsi-meet/issues/4049

* ref(feedback): emit api feedback submitted on completion

Compared to firing the event on submission because
the submission ajax will not be completed at that
time..

* squash: update package.json

- Use actions to notify the rest of the app that
  a mic or camera error has occurred
- Use middleware to respond to those notifications
  of errors by showing in-app notifications and
  notifying the external api
