fix: remove custom node_exporter, standardise on package version (#40 )

london-b had both a custom node_exporter.service and the
package-managed prometheus-node-exporter.service installed.
Both tried to bind port 9100, causing the package version to fail.

- Add cleanup tasks to remove custom /etc/systemd/system/node_exporter.service
  and /usr/local/bin/node_exporter if present
- Add node_exporter_extra_collectors variable for configurable collectors
- Configure london-b with systemd/processes/sysctl/ethtool/zfs collectors
  matching its previous custom setup

Resolves PESO-109
