Parsing the sysfs files for InfiniBand was added to the procfs library
(see https://github.com/prometheus/procfs/pull/164).
Therefore use `InfiniBandClass` from the procfs library instead of
parsing sysfs itself.
If the port counter return `N/A (no PMA)` no metric will be returned
(instead of returning 0 for this metric.

As per https://github.com/prometheus/node_exporter/pull/1429#discussion_r304210103
we want to fetch all devices and all fs types.
Currently, this is done by setting empty string which breaks most queries which rely on it.
This fixes it by setting the appropriate selector instead of empty string.

The dbus property 'SystemState' and the timer property 'LastTriggerUSec'
were added in version 212 of systemd.
Check that the version of systemd is higher than 212 before attempting
to query these properties

- Use a stacked graph instead of a gauge as development over time is
especially useful for disk space usage.
- By only taking one metric per device into account, we avoid
double-counting for devices that are mounted multiple times.

* node-mixin: Improve nodes dashboard
- Use stacking where it makes sense.
- Normalize idle CPU so that stacking is more meaningful.
- Consistently fill where stacking is used but don't fill where not.
- Fix y axis max value for Idle CPU panel.
- Fix y axis min value for memory usage panel.
- Use `$__interval` for range where applicable (and set min step
to 1m).
- Make the right Y axis for disk I/O actually work.
This is just an incremental improvements. It doesn't touch the more
involved TODOs.

This addresses the blissful scenario where single-node failures are
unproblematic. No reason to wake somebody up if a node is about to
screw itself up by filling the disk.

- Normalize cluster memory utilisation.
- Fix missing `1m` in memory saturation.
- Have both disk-related row next to each other instead with the
network row in between.
- Correctly render transmit network traffic as negative, using
`seriesOverrides` and `min: null` for the y-axis.
- Make panel and row naming consistent.
- Remove legend where it would just display a single entry with
exactly the title of the panel.
- Fix metric name in individual node CPU Saturation panel.
- Break up disk space utilisation by device in the panel for an
individual node.
NB: All of that doesn't touch any more subtle issues captured in the
various TODOs.

Use the extra information gleaned from the mountinfo file to add
a 'mountaddr' field for NFS metrics. This helps prevent prometheus from
ignoring mounts that come from the same URL, but are actually from
different IP addresses.

As per prometheus/client_golang#543, pass the Registry for exporter
metrics when setting up the /metrics HTTP handler.
With this, the `promhttp_metric_handler_errors_total` metric will
increment on (possibly non-fatal) collection-time errors, such as
duplicate metrics from text files.

This will cause a query to be valid even if values of selector are
empty.
Additionally fixing query responsible for disk space usage.
