Configure calls plugin for Mattermost

Simple case of Single-instance Team edition

Setting	Value
RTC Server Address	`0.0.0.0` or `[::]`
RTC Server Port	Leave blank for `8443` default, or change to another available port
ICE Host Override	Your chat server's host name, e.g. `mm.organisation.example`, unless that may not resolve to your public IP address when queried locally on that server. The latter can occur if you have an entry in your `hosts` file that resolves to a loopback address, or split-horizon DNS, in which case you need to enter the IP address or a different (sub)domain that always resolves to it, e.g. `calls-mm.organisation.example`.
ICE Servers Configurations	Leave blank

Quick setup of Mozilla's APT repository

The easy way to enable installation of packages, adapted from [Mozilla's guide][1]. Files should be saved to:

/etc/apt/preferences.d/mozilla
/etc/apt/sources.list.d/mozilla.sources

The PGP key is [Mozilla's][2], which you can compare to the one embedded in the .sources file.

EKM Global DCA on Alpine Linux

Assumes you have Alpine set up and running. I use a little VM so the DCA can have the privileges it wants and not interfere with anything else, but you might want to use Docker, etc.

The default installer failed, and when I got it working, the service would not stay up. This is what I did to get it going.

Copy the relevant installer URL from [EKM's updates site][1].
Fetch it.
