Currently Node Exporter has a metric called `node_uname_info` which of
course exposes uname info. While this is nice, it does not help if you
are running different OSes which could have similar uname info.
Therefore parse `/etc/os-release` or `/usr/lib/os-release` and expose a
`node_os_info` metric which provide information regarding the OS
release/version of the node. Also expose the major.minor part of the OS
release version as `node_os_version`.
Since the os-release files will not change often, cache the parsed
content and only refresh the cache if the modification time changes.
This `os` collector will read files outside of `/proc` and `/sys`, but
the os-release file is widely used and the format is standardized:

In high scale virtualized / cloud environments there are typically
no guest VMs. Add a boolean flag to allow disabling the Linux guest
CPU metrics.

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.

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

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.
