Add a DMI collector to expose the Desktop Management Interface (DMI)
info from `/sys/class/dmi/id/`. This will expose information about the
BIOS, mainboard, chassis, and product.

The ethtool_cmd struct from the linux kernel contains information about the speeds and features supported by a
network device. This includes speeds and duplex but also features like autonegotiate and 802.3x pause frames.

* collector: Unwrap glob textfile directories
* collector: Store full path in mtime's file label
The point is to avoid duplicated gauges from files with the same name in
different directories.
This introduces support for exporting from multiple directories matching
given pattern (e.g. `/home/*/metrics/`).

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:

* Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes.
For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue.
@SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing.
The names of the new TCP states and the UDP metric can be discussed.
The current reasons are just:
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.

The `node_cpu_info` metric contains some information like the `model`
(which is an integer), but not the human readable model name. Also the
stepping of the processor might be interesting, since different stepping
of a processor might behave differently.
