It seems like it doesn't cause any issues for any of these services.

The quotes around "host" for both `--pid` and `--net` were
causing trouble for me:

> docker: --pid: invalid PID mode.

and:

> docker: Error response from daemon: network "host" not found.

I've also changed the `-v` call to `--mount` for consistency with the
rest of the playbook.

Changed `matrix_mautrix_signal_docker_image_force_pull` to `matrix_mautrix_signal_daemon_docker_image_force_pull` when force pulling the daemon

Using the hardcoded IP did break while I was
messing with IPv6 stuff on the other branch

By running it in a more privileged container with access to the host network stack and such

Also includes the dashboards for Synapse and for Node Exporter.

Again has only been tested on debian amd64 so far, but the grafana docker image is available for arm64 and arm32. Nice.

Basic system stats, to show stuff the synapse metrics
can't show such as resource usage by bridges, etc

Seems to work fine as well.

This too has only been tested on debian amd64 so far

Initial attempt. Seems to work fine.

Only tested on debian amd64 so far

This will make data migration easier.

This passes any arguments given to 'matrix-postgres-cli' to the 'psql' command.

Examples:
  $ # start an interactive shell connected to a given db
  $ sudo matrix-postgres-cli -d synapse
  $ # run a query, non-interactively
  $ sudo matrix-postgres-cli -d synapse -c 'SELECT group_id FROM groups;'

If they do, our next playbook runs would simply revert it
and report "changed" for that task.

There's no benefit to letting the bridge spew a new config file.

This does not apply to the mautrix whatsapp bridge, because that one
is written in Go (not Python) and takes different flags. There's no
equivalent flag there.

Future maintainer: check on https://docs.docker.com/engine/install/debian/ if Docker for
Debian 11 is released, then undo this commit

Fixes:
https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/833

The default scalar.vector.im integrations manager doesn't support custom
URL's for etherpad, therefore Dimension needs to be enabled.

Regression since f6097fbba1

Fixes a regression introduced in f6097fbba1fb, which was cauing Synapse
to die with this error message:

> ValueError: sender_localpart needs characters which are not URL encoded.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/806

These are just defensive cleanup tasks that we run.
In the good case, there's nothing to kill or remove, so they trigger an
error like this:

> Error response from daemon: Cannot kill container: something: No such container: something

and:

> Error: No such container: something

People often ask us if this is a problem, so instead of always having to
answer with "no, this is to be expected", we'd rather eliminate it now
and make logs cleaner.

In the event that:
- a container is really stuck and needs cleanup using kill/rm
- and cleanup fails, and we fail to report it because of error
suppression (`2>/dev/null`)

.. we'd still get an error when launching ("container name already in use .."),
so it shouldn't be too hard to investigate.

I don't think this was causing an issue, but it might
if the bot token has a more special value in the future.
