Title: Convert spaces found in the Ganglia Group (source) to underscores before sending to Graphite.

If the Ganglia Grid / Group for any given metric has spaces in the name e.g.
data_source "Development Servers", this space will be rejected by Graphite.
This patch converts spaces to underscores "_" to allow these metrics to be accepted by Graphite.
