prometheus-node-exporter: Support extra options.
There are plenty of options supported that the Guix configuration record doesn't help you with, so add this field to allow users to do their own thing. * gnu/services/monitoring.scm (<prometheus-node-exporter-configuration>): Add extra-options field. (prometheus-node-exporter-shepherd-service): Handle the extra options. * doc/guix.texi (Prometheus Node Exporter Service): Document this.
