Add a `node_ethtool_info` metric to all ethtool devices to expose driver
information with following labels:
* bus_info
* driver
* expansion_rom_version
* firmware_version
* version
This metric is useful to monitor the firmware version to be up-to-date.
Note: The version label might be malformed due to bug #39 in ethtool:

OpenMetrics and the Prometheus exposition format require the metric name
to consist only of alphanumericals and "_", ":" and they must not start
with digits. The metric names from the ethtool stats might contain
spaces, brackets, and dots. Converting them directly to metric names
will produce invalid metric names.
Therefore sanitize the metric names and convert them to lower case.

This adds a new flag --collector.ethtool.metrics-include to the ethtool
collector. Only metrics matching this regexp will be collected.

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.
Fixes#1891

We should filter excluded interfaces before parsing the interface
details.
