This updates the annotation for the NodeClockSkewDetected mixin alert to
match the new threshold set.
Original discussion was in this PR: https://github.com/prometheus/node_exporter/pull/1480
I spent an embarrassingly large amount of time trying to figure out how
the heck that alert would mean 300s of clock skew. Turns out the
annotation was just left the same after the threshold change.

* docs/node-mixin: add fsMountpointSelector
This adds the option to add a `mountpoint` selector to filesystem
related alerts. The default is `mountpoint!=""`.

When appying rate() to seconds we have 'seconds per second' or fractions of the second, so actually it actually can be from 0 to 1.
Also update intervalFactor to 1 for better rates.

rate() calculates per-second average rate, therefore Bps units should be used for disks.
In networking bandwidth throughput is usually measured in bits/s so units are changed accordingly.

Problem: In 0b50eb7294 the usage of the
threshold variables was adjusted. The values had been switched as well
resulting in reversed thresholds after the commit above. Warnings now
have a smaller threshold than critical alerts.
Solution: Adjust thresholds to reflect that warnings should be alerted
on before critical alerts.

Currently critical alert for space available alerts on warning and
warning alert for space available alerts on critical.

'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.

This should be the way forward when importing libraries in jsonnet. It's
closer to how Go imports look and makes it more obvious where packages
live.
This is not breaking anything, as the old imports were already symlinks
to the now directly used directories.
