Bug Description

we store previous sample data in local memory. this isn't very resilient if:

a) an agent goes down, we lose that 'cache'
b) distribution changes, the agent may start working on a different set of resources

we could make this better by either writing to disk occasionally OR connecting to redis

whoops sorry, didn't see this.

i think this is superseded by gnocchi. whatever we do here would be replicating part of the functionality of gnocchi. it's essentially be a lesser version of it.

marking won't fix as you can just compute most transforms such as rate in gnocchi itself.
