Add DMI collector (#2131)
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.

Add gauges for allocated memory for queued UDP and TCP packages (#1503)
* 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.

Fix num cpu (#1561)
* 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.
