This adds a new Linux metric, node_softirqs_total, which corresponds
to the 'softirq' line in /proc/stat. This metric is disabled by
default and it can be enabled with '--collector.stat.softirq'.

TCP timeouts count is a useful signal to show
abnormal network performance and is another
signal to aid debugging. This metric can be
used to generate proactive alerts for host
network namespace workloads.

The new `lnstat` collector produces a high number of metrics, per-cpu,
and results in approximately double the number of metrics previously
scraped. For example, a typical server with 64 cores produces 3832
lnstat metrics compared to 4147 metrics for the remaining collectors.
Therefore disable the `lnstat` collector by default.

Sanitizing the metric names can lead to duplicate metric names:
```
caller=level.go:63 level=error caller="error gathering metrics: [from Gatherer #2] collected metric \"node_ethtool_giant_hdr\" { label:<name:\"device\" value:\"ens192\" > untyped:<value:0" msg=" > } was collected before with the same name and label values"
```
Generate a map from the sanitized metric names to the metric names from
ethtool. In case of duplicate sanitized metric names drop both metrics,
because it is unknown which one to take.

Use SysctlTimeval from the golang.org/x/sys/unix package to

allows to build it without cgo.

'iowait' and 'steal' indicate specific idle/wait states, which shouldn't
be counted into CPU Utilisation. Also see
https://github.com/prometheus-operator/kube-prometheus/pull/796 and
https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/667.
Per the iostat man page:
%idle
Show the percentage of time that the CPU or CPUs were idle and the
system did not have an outstanding disk I/O request.
%iowait
Show the percentage of time that the CPU or CPUs were idle during
which the system had an outstanding disk I/O request.
%steal
Show the percentage of time spent in involuntary wait by the
virtual CPU or CPUs while the hypervisor was servicing another
virtual processor.

The point is to avoid duplicated gauges from files with the same name in
different directories.
This introduces support for exporting from multiple directories matching
given pattern (e.g. `/home/*/metrics/`).
