> Create a new {{nodetool profileload}} that functions just like toppartitions
> but with more data, returning the slowest local reads and writes on the host
> during a given duration and highest frequency touched partitions (same as
> {{nodetool toppartitions}}). Refactor included to extend use of the sampler
> for uses outside of top frequency (max instead of total sample values).
> Future work to this is to include top cpu and allocations by query and
> possibly tasks/cpu/allocations by stage during time window.
