Increase the async timeout value defaults, as larger Matrix servers need more time to complete.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/1749

This update brings stable threads support

Tested, works without any configuration changes.

https://github.com/matrix-org/matrix-hookshot/releases/tag/1.4.0

We no longer validate that there's an IP address defined.
Seems like Coturn can start without one as well, so there's no need to
require it.

If people populate `matrix_coturn_turn_external_ip_addresses` directly
to specify multiple addresses, they can leave
`matrix_coturn_turn_external_ip_address` empty.

We use the "select not equal to empty string" thing in the for loop
to avoid `matrix_coturn_turn_external_ip_address` leading to
`matrix_coturn_turn_external_ip_addresses: ['']` leading to
`external-ip=` in the Coturn configuration.

People often report and ask about these "failures".
More-so previously, when the `docker kill/rm` output was collected,
but it still happens now when people do `systemctl status
matrix-something` and notice that it says "FAILURE".

Suppressing to avoid further time being wasted on saying "this is
expected".

Add support for multiple external turn IP addresses, this allows for better comptability with dualstack ipv4/ipv6 hosts, and is supported as per the documentation (point 6 here: https://matrix-org.github.io/synapse/latest/turn-howto.html#configuration)

This reverts commit 0103d92df4.

The same fix has now been merged upstream
(https://gitlab.com/beeper/mx-puppet-monorepo/-/merge_requests/35), so
we don't need to use a fork anymore.
