Pr 586 tweaks (#594)

Browse Source 
* add proxy tcp

* add truncated for tcp to udp response

* move truncation to scrubbing

* add test that executes upstream over tcp

* middleware/proxy: some tweaks

rename force-tcp to force_tcp to be inline with the rest and use
a dnsOptions struct to put the options in to allow it to be extended.
Add some parse tests as well.

* Fix test and rename dnsOptions Options
