Sam Kottler 6eafa51fa8 Add ARP collector for Linux (#540)
* Implement commonalities and linux support for ARP collection

* Add ARP collector to fixtures and run as part of e2e tests

* Bubble up scanner errors

* Use single return values where it makes sense

* Add missing annotation

* Move arp_common into arp_linux

* Add license header to arp_linux.go

* Address initial feedback

* Use strings.Fields instead of strings.Split

* Deal with scanner.Err() rather than throwing away errors

* Check for scan errors in-line before interacting with the entries map

* Don't interact with potentially empty text from scan

* Check for scan errors outside the scan loop

* Add comment about moving procfs parsing

* Add more direct comment

* Update initialism style to match go style guide

* Put function args on the same line

* Add TODO in front of comment about procfs extraction

* Guard against strings.Fields returning an empty slice

* Be more defensive about ARP table format and use upcase more broadly

* Enable the ARP collector by default

* Add ARP collector to the README

* Remove 'entry'

Ben Kochie 5f43211f67 Blacklist systemd scope units
Blacklist `scope` units from systemd collector by default.

These units are created with unique IDs programatically[0].  This leads to
huge cardinality problems.

Tobias Schmidt d290ea94b8 Fix export of stale device error metrics for unmounted filesystems
Instead of maintaining a counter metric for device errors in memory,
this change exports a gauge and uses const metrics to avoid leaking
metrics for unmounted filesystems.

Robert Clark 3a5917dfdc Add support for legacy InfiniBand drivers
Older versions of the OFED drivers contain 64-bit variants of the port counters and are located in a directory named 'counters_ext'. This patch includes these older metrics that have since been deprecated with OFED 4.0.

further, e.g. `err error` doesn't add any new information and is just
