Gnocchi can capture rate information and can also have mathematical 
operations applied to it. there are some examples here: 
https://gnocchi.xyz/rest.html#examples. i imagine we'll change the gate 
workflow to that eventually.

you will still need partitioning for HA of central agents... and 
currently, the only way to get batch support is with workload_partitioning.

but yes, moving the transformation to storage will provide the most 
durable solution for transformations.
