Initial work on a vertica backend.
Played with a couple more aspects of the code including a fancier query.
Mostly the organization and integration into graphite is still messy.
Minor query cleanup
A bit of cleanup
a bit smarter on my pyodbc connections.
reader query cleanup
Initial setup of building a tree from metricDefinitions and not using
the entites table at all.
better message for missing data.
Initial solution using a view in the db for building the tree.
Added the metrics table name as config variable
Comment cleanup
I needed to deal with empty strings in the leaf path also.
Made the depth of the tree configurable so I can just change the view to
get a better tree.
