Other network related collectors allow to filter out unwanted devices.
Add this support to the new ethtool collector as well.

Update procfs library to include ignored fields ParseInt handling.
Wrap error returns so that the user can know more about what failed.
Returns from getAllocatedThreads() are errors anyway.

NOTE: Ignoring invalid network speed will be the default in 2.x
NOTE: Filesystem collector flags have been renamed. `--collector.filesystem.ignored-mount-points` is now `--collector.filesystem.mount-points-exclude` and `--collector.filesystem.ignored-fs-types` is now `--collector.filesystem.fs-types-exclude`. The old flags will be removed in 2.x.

The Linux CPU idle stat can also jump backwards slightly in some cases.
Allow the jump back up to 3 seconds before we attempt to reset the CPU
counter cache.

Add a collector for NVMes to expose the firmware versions. This requires
procfs >= 0.7.0.

We should filter excluded interfaces before parsing the interface
details.

When /metrics is called for specific collectors, the collectors are
initialed every time. Which means that we spend a lot of time
re-initiating the same collectors again and again. Especially, some
collectors make the assumptions that that are initiated once - e.g.
systemd collector generates info message upon initiation.
