Greatly trim what netstat collector exposes by default (#876)

Netstat is 40% of the metrics on my laptop, many of which
are highly detailed information about IP internals in the kernel.
~300 such metrics on every machine in your fleet is excessive,
so focus on key metrics by default, overridable by the user.

Fixes #515
