Description
Is your feature request related to a problem? Please describe
For concurrent segment searches, the profiling information is limited to the times for each phase in the query and the statistics across the slices. However, there are not information on the internals of the slices.
Describe the solution you'd like
Should there be information on the segments in each of the slices the query ran? With the incoming feature of intrasegment concurrent search worked on by @prudhvigodithi , should there also be information on the partitions of the segments search on?

Research direction
Start by reviewing the existing profiling output for concurrent segment searches and the related intrasegment concurrent-search work mentioned in the issue. Trace how timings and slice statistics are collected, then determine the scope and format for reporting segment and partition details. Done means the requested profiling information is defined, implemented, and covered by appropriate tests.
