The new variable has a better purposed name, and supports a comma
separated list of IPs instead of a single one, which should help those
running split-horizon setups.
* Migrating configuration to use secure octo configuration by default
Adding a new JVB_OCTO_RELAY_ID to configure videobridge.relay.relay-id (with a fallback to the old JVB_OCTO_BIND_ADDRESS to be used as relay-id)
* Adding a configuration check to verify that Octo cannot be enabled without the ENABLE_COLIBRI_WEBSOCKET environment variable set to "1"
NAT_HARVESTER_LOCAL_ADDRESS needs to bet set to the local IP that is actually
used to communicate with clients.
In Docker containers "hostname -I" returns the IPs of all interfaces. The order
of the IPs depends on the interface create order.
Docker makes no guarantees about the interface order and in my tests it is
random.
As a result NAT_HARVESTER_LOCAL_ADDRESS is sometimes set to the IP of the
internal meet.jitsi interface.
Fix this by setting it to the source IP used for routing to $DOCKER_HOST_ADDRESS
Adds 2803 kB disk space for iproute2 and dependencies.
