Slavi Pantaleev b1b4ba501f Replace ExecStop with ExecStopPost
ExecStopPost should allow us to clean up (docker kill + docker rm)
even if the ExecStart (docker run ..) command failed, and not just after
a graceful service stop was initiated.

Raymond Coetzee 4e2780ff88 Add support for a prometheus postgres exporter
This commit introduces a new role that downloads and installs the
prometheus community postgres exporter  https://github.com/prometheus-community/postgres_exporter.
A new credential is added to matrix_postgres_additional_databases that
allows the exporter access to the database to gather statistics.
A new dashboard was added to the grafana role, with some refactoring
to enable the dashboard only if the new role is enabled.
I've included some basic instructions for how to enable the role in
the Docs section.

In terms of testing, I've tested enabling the role, and disabling
it to make sure it cleans up the container and systemd role.

Slavi Pantaleev df3dd1c824 Use --read-only FS for metrics-related containers
It seems like it doesn't cause any issues for any of these services.

Peetz0r 144a5e6198 Register docker network info and use it for prometheus-node-exporter
Using the hardcoded IP did break while I was
messing with IPv6 stuff on the other branch

Peetz0r 76d7e84be5 Make prometheus-node-exporter a bit more capable
By running it in a more privileged container with access to the host network stack and such

Peetz0r e525970b39 Prometheus Node Exporter
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
