* netstat: Add TCP In/Out Segs
In order to get a better idea of TCP packet loss, we need to know how
many `node_netstat_Tcp_OutSegs` there are so we can compare this to
`node_netstat_Tcp_RetransSegs`.

* Add fallback for missing /proc/1/mounts
On some systems, `/proc/1/mounts` is hidden from non-root users due to
the `hidepid` procfs feature. Attempt to fallback to `/proc/mounts` if
`/proc/1/mounts` is not found.

The pull request #1002 changed the logic used on Linux servers to determine if a filesystem is
read-only. As a result of this change, the variable `readOnly` is now unused and can be removed.

We use the output-compatible perccli and storcli.py does not handle 'Unknown' as a result:
```
sg="Error parsing \"/var/lib/node_exporter/perccli.prom\": text format parsing error in line 222: expected float as value, got \"Unknown\"" source="textfile.go:212"
```
I know, the perccli should not return 'Unknown' but this error breaks all other useful measurements because the prom file is not parsable. My if condition fixes this.

In order to avoid stuck collectors using up all system resources, add a
limit to the number of parallel in-flight scrape requests. This will
return a 503 error.
Default to 40 requests, this seems like a reasonable number based on:
* Two Prometheus servers scraping every 15 seconds.
* Failing scrapes after 5 minutes of stuckness.

If this flag is set, the metrics about the exporter itself (go_*,
process_*, promhttp_*) will be excluded from /metrics.
The Kingpin way of handling boolean flags makes the negative flag
wording (_dis_able) the most reasonably one.
This also refactors the flow in node_exporter.go quite a bit to avoid
mixing up the global and a local registry and to avoid re-creating a
registry even if no filtering is requested.

Tcp SYN packet retransmits are a very useful signal as they affect
network performance disproportionately to regular TCP retransmits.

In some cases the file might be called "temp" instead of the usual format "temp<index>_<item>"
as described in the kernel docs: https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface
In this case, treat this as an _input file containing the current temperature reading.
