Add -q0 option to nc in docs

With some versions of nc, the connection is kept open after all data is sent. Using -q0 parameter will make nc quit immediatly after EOF on stdin.

Debian has two debian packages for nc: netcat-traditional and netcat-openbsd. The former hangs after EOF on stdin, whereas the latter quits. I assume the expected behavior is to quit nc after sending the metric data.

Docs/tools: add pipe-to-graphite

We wrote [pipe-to-graphite](https://github.com/iFixit/pipe-to-graphite)
a while ago to make it easy to record the output from the status
commands of gearmand, memcached, varnish, etc.  I don't know why we
never added it to the list of tools, so here it is.
