   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
   
   
   ### Motivation
   
   While researching the solution for #18236, it would have been very helpful to have access to a cursor's persisted `PositionInfo` in Bookkeeper. In that bug's case, the persisted data in bookkeeper didn't align with the `PositionInfo` persisted in zookeeper, and verifying that was essential to finding the bug.
   
   ### Solution
   
   I see two options:
   
   1. Create a new admin http endpoint that allows a user with super user privileges permission to get a range of persisted entries from a cursor's ledger. The primary benefit of this solution is that it gives us the ability to investigate historical `PositionInfo`, which could be very helpful.
   2. Update the `stats-internal` admin http result to also include the most recently persisted `PositionInfo`. One risk for this solution is that it increases the cost of `stats-internal`. However, that command is already a troubleshooting command, so that should be fine.
