Change subject: Introduce a hourly storage schema in graphite
......................................................................
Introduce a hourly storage schema in graphite
Maps needs to collect hourly metrics.
This introduces an hourly schema which can be used to store hourly metric,
with 1-day aggregation after 1 year. This follows the same pattern as the
existing daily schema.
The space gained by this is fairly small (130k per metric vs 300k per metric
for the default schema), but will help not having holes in time series for
metrics collected hourly.
