* 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.

* add a map of profilers to CPUids
`runtime.NumCPU()` returns the number of CPUs that the process can run
on. This number does not necessarily correlate to CPU ids if the
affinity mask of the process is set.
This change maintains the current behavior as default, but also allows
the user to specify a range of CPUids to use instead.
The CPU id is stored as the value of a map keyed on the profiler
object's address.

Many collectors depend on underlying features to be enabled. This causes
confusion about what "success" means. This changes the behavior of the
`node_scrape_collector_success` metric.
* When a collector is unable to find data don't return success.
* Catch the no data error and send to Debug log level to avoid log spam.
* Update collectors to support this new functionality.
* Fix copy-pasta mistake in infiband debug message.

Integer division and the order of operations when converting Mbps to Bps
results in a loss of accuracy if the interface speeds are set low.
e.g. 100 Mbps is reported as 12000000 Bps, should be 12500000
10 Mbps is reported as 1000000 Bps, should be 1250000

Use the extra information gleaned from the mountinfo file to add

ignoring mounts that come from the same URL, but are actually from
different IP addresses.
