[collectd] Output plugin for submitting values to an http server

[Paul Sadauskas]

Hi list,

I've been working on a plugin that submits values to an HTTP server
using POST. It uses the plain-text protocol described here:
http://collectd.org/wiki/index.php/Plain_text_protocol

To save network overhead, it batches up values, and submits them all at once.

octo already made a branch, ps/http, and I have a few more patches on
my github branch: http://github.com/absperf/collectd/tree/http

Thanks,
Paul
