What this PR does / why we need it:
Fixes the Graphite sorting and reduce functions to be deterministic if there is multiple ranked series at the same sort order. This is done by using sort.Stable and if there was no incoming sort order into the function then applying sort by name to have determinism on which sort.Stable will pick as results.
