NFV configuration benchmark

[eugeneia]

This branch factors out load_config from designs/neutron/snabbnfv_traffic to lib.nfv.config.load/lib.nfv.config.apply and adds a benchmark designs/bench/nfvconfig which measures their performance.

This branch also fixes a few bugs in related code paths.

See this wiki page.

That is wrong indeed, it works if you swap x and y in the second loop but maybe it should just compare #x == #y?

The Lua # operator returns creative results when applied to something that
is not an array indexed by 1,2,3,4...

Fixed here (also added a regression test): #247

equal() looks good to me now!
