[LI-HOTFIX] Add visibility to usage of ListOffsets by timestamp

[lmr3796]

LI_DESCRIPTION = LIKAFKA-54997
EXIT_CRITERIA = When such information is no longer needed

For the Northguard use case, we want to know what's the load on ListOffsets API used with "search by timestamp".
This patch exposes the visibility to

1. Partitions per second requested for listOffset by each type (earliest, by timestamp, latest, etc.)
2. Exposes the logging for "what are the principals querying such case"
3. Distribution of partitions included per request.

Summary of testing strategy (including rationale)
