Support sending usage metrics to graphite

[jbrogan]

I am running this once a day and sending the metrics to graphite for long term trending.

I'd like to add support for the following arguments:

--graphite-url <ip:port>
--graphite-prefix os-swift 
--graphite-suffix daily 
--cluster-name os-r-object

For these arguments, this is the metric namespace you would have in graphite.

os-swift.os-r-object.container_amount.daily
os-swift.os-r-object.account_min_size.daily
os-swift.os-r-object.total_size.daily
...

Let me know if you would find this useful as an enhancement.

Hi John,

Oh sorry, I haven't caught your issue since January :/ ... I need to check where
the notification are sent ...
So yes I think it could be a great piece of improvement so if you have code for that
feel free to contribute as I think it will be really useful for everyone !

Thanks a lot John,
Cheers,
Fabien
