We're looking to reuse this in Cortex to client side encrypt our
connections and not having this exposed is making us copy this entire
function.

The readme file does not mention the need to create a folder named
/var/lib/node_exporter/textfile_collector as a step. Lack of this
folder results errors for node_exporter service which is visible
in systemd status output. These errors possibly harmless but it is
not good to have them still.
$ sudo systemctl status node_exporter

* Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes.
For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue.
@SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing.
The names of the new TCP states and the UDP metric can be discussed.
The current reasons are just:
I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector.
I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state.

The `node_cpu_info` metric contains some information like the `model`
(which is an integer), but not the human readable model name. Also the
stepping of the processor might be interesting, since different stepping
of a processor might behave differently.

* Make FS space alerts thresholds configurable (#1)
This makes it possible to tweak the thresholds for
the NodeFilesystemSpaceFillingUp alerts. Which
might be necessary in systems like Kubernetes,
where the image garbage collector runs at 85%,
so it's not a problem that the disk reaches that usage %.

* add a map of profilers to CPUids
`runtime.NumCPU()` returns the number of CPUs that the process can run
on. This number does not necessarily correlate to CPU ids if the
affinity mask of the process is set.
This change maintains the current behavior as default, but also allows
the user to specify a range of CPUids to use instead.
The CPU id is stored as the value of a map keyed on the profiler
object's address.

Many collectors depend on underlying features to be enabled. This causes
confusion about what "success" means. This changes the behavior of the
`node_scrape_collector_success` metric.
* When a collector is unable to find data don't return success.
* Catch the no data error and send to Debug log level to avoid log spam.
* Update collectors to support this new functionality.
* Fix copy-pasta mistake in infiband debug message.
