* Add /proc/swaps collector
Building on prometheus/procfs#246 this PR is introducing metrics around swap devices.
Today metrics around swap are already available, but they are on the node level.
With this PR, metrics are now available per device.

* Add collector for PCIe devices with link information
The link status of PCIe devices sometimes changes,
like link or speed downgrades, and devices disappear.
This patch collects PCIe devices' link infromation to detect such failures.
As a first step, this collector exports PCIe devices'
- Device information (vendor_id, device_id, etc.)
- Parent PCIe device (e.g. PCIe bridge, PCIe switch)
- Link status (max_link_{transfers_per_second|width}, current_link_{transfers_per_second|width})

Add support for allow lists of filesystem mount points and filesystem
types. This allows for less messy regexps when you want to target only
specific lists of mount points or filesystem types.

This PR adds a `exclude[]` URL parameter to exclude specific enabled collectors.
Compared to `collect[]` parameter, the `exclude[]` parameter results in a filtered list which equals enabled collectors minus excluded ones.

* Add include and exclude filter for sensors in hwmon collector
Fixes #2242
This commit adds two new flags (`collector.hwmon.sensor-include` and `collector.hwmon.sensor-exclude`) to the `hwmon` collector to allow inclusion or exclusion of specific sensors.
Some devices export nonsensical values for certain sensors. Here is an example:
```
node_hwmon_temp_celsius{chip="platform_nct6775_656",sensor="temp13"} 49.75
node_hwmon_temp_celsius{chip="platform_nct6775_656",sensor="temp15"} 3.892313987e+06
node_hwmon_temp_celsius{chip="platform_nct6775_656",sensor="temp16"} 3.892313987e+06
```
As a user I would like to only exclude these sensors, not necessarily the complete device (as is currently possible with the `--collector.hwmon.chip-exclude` flag) as other sensor values might be sensical or desired.
The new option filters based both on device name and sensor name, separated by a semicolon. For example, to exclude the two sensors above, the following regex can be used:
~~~
--collector.hwmon.sensor-exclude="platform_nct6775_656;temp1[5,6]"
~~~

The ntp collector has always been a source of confusion and problems.
The data it produces is more of a blackbox probe against an NTP server.
The time sync / offset data produced is not what users expect.

The new `lnstat` collector produces a high number of metrics, per-cpu,
and results in approximately double the number of metrics previously
scraped. For example, a typical server with 64 cores produces 3832
lnstat metrics compared to 4147 metrics for the remaining collectors.
Therefore disable the `lnstat` collector by default.

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:

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:
