[collectd] Varnish 3.0 support

[Jerome Renard]

Good evening,

I worked on a varnish 3.0 compatible plugin. It is also compatible
with Varnish < 3.0.

You can get it at the following URL:
- https://github.com/jeromer/collectd/

The plugin is available in the jr/varnish3.0 branch:
- https://github.com/jeromer/collectd/tree/jr/varnish3.0

Florian : feel free to comment the code as much as you want :)

Best Regards,
