> 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.
