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.
