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.

Slavi Pantaleev adcecaffaf Fix connectivity between prometheus and prometheus-node-exporter 
Expected to have regressed after https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1008

This patch comes with its own downsides (as described in the comments
for matrix_prometheus_node_exporter_container_http_host_bind_port),
but at least there's:
- no security issue
- metrics remain readable from matrix-prometheus (even if the network metrics are inaccurate)

A better patch is certainly welcome.

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.

Slavi Pantaleev f0cd294628 Fix matrix-prometheus-node-exporter failure to start 
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.

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
