TCP timeouts count is a useful signal to show
abnormal network performance and is another

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.

Sanitizing the metric names can lead to duplicate metric names:
```
caller=level.go:63 level=error caller="error gathering metrics: [from Gatherer #2] collected metric \"node_ethtool_giant_hdr\" { label:<name:\"device\" value:\"ens192\" > untyped:<value:0" msg=" > } was collected before with the same name and label values"
```
Generate a map from the sanitized metric names to the metric names from
ethtool. In case of duplicate sanitized metric names drop both metrics,
because it is unknown which one to take.

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:

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

will produce invalid metric names.
Therefore sanitize the metric names and convert them to lower case.

I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector.
I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state.

Parsing the sysfs files for InfiniBand was added to the procfs library
(see https://github.com/prometheus/procfs/pull/164).
Therefore use `InfiniBandClass` from the procfs library instead of
parsing sysfs itself.
If the port counter return `N/A (no PMA)` no metric will be returned
(instead of returning 0 for this metric.

Use the extra information gleaned from the mountinfo file to add
a 'mountaddr' field for NFS metrics. This helps prevent prometheus from
ignoring mounts that come from the same URL, but are actually from
different IP addresses.

As per prometheus/client_golang#543, pass the Registry for exporter
metrics when setting up the /metrics HTTP handler.
With this, the `promhttp_metric_handler_errors_total` metric will
increment on (possibly non-fatal) collection-time errors, such as
duplicate metrics from text files.

* Closes issue #261 on node_exporter.
Delegated mdstat parsing to procfs project. mdadm_linux.go now only exports the metrics.
-> Added disk labels: "fail", "spare", "active" to indicate disk status
-> hanged metric node_md_disks_total ==> node_md_disks_required
-> Removed test cases for mdadm_linux.go, as the functionality they tested for has been moved to procfs project.

* Add --collector.netdev.device-whitelist flag
Sometimes it is desired to monitor only one netdev. The golang regexp
does not support a negated regex, so the ignored-devices flag is too
cumbersome for this task.
This change introduces a new flag: accept-devices, which is mutually
exclusive to ignored-devices. This flag allows specifying ONLY the
netdev you'd like.

Previously, the node_textfile_mtime_seconds metric was based on the
Fileinfo.ModTime() of the ioutil.ReadDir() return value. This is based
on lstat() and therefore has unintended consequences for symlinks
(modification time of the symlink instead of the symlink target is
returned). It is also racy as the lstat() is performed before reading
the file.
This commit changes the node_textfile_mtime_seconds metric to be based
on a fresh Stat() call on the open file. This eliminates the race and
works as expected for symlinks. Fixes#1324.

The cpu frequency information is not always needed and/or available.
This change allows the cpu frequency metrics to be enabled/disabled
separately from the other cpu metrics, and also prevents a frequency
metric failure (such as a parse error) from failing the main cpu
collector.

This reduces the system metric collection time by using a wait group
and go routines to allow the systemd metric calls happen concurrently.
Also, makes the start time, restarts, tasks_max, and tasks_current metrics disabled by default
because these can be time consuming to gather.

With a bond interface the state of the slave interface from the bond's
point of view is reflected in `mii_status` and is independent of the
link's `operstate`.
When a bond is monitored with `miimon`, `mii_status` will reflect the
state of the physical link as configured via the operator.
When a bond is monitored via `arp_interval` the `mii_status` will
reflect the results of the bond ARP checking. This means the link can
be down from the bond's point of view, but up from a physical
connection point of view.
If a bond is not monitored via miimon or arp, the `mii_status` should
likely be always `up`, however I have observed a case where this is not
true and the `operstate` is `up` while `mii_status` is `down`. Kernel
bond documentation stresses that a bond should not be configured without
one of `mii_mon` or `arp_interval` configured however.
This change results in the metric 'node_bonding_active' matching the
up/down state of the bond's point of view rather than operstate.
