Description
Currently it is not possible to create a ReaderManager instance on a given IndexCommit. Since the ReaderManager is final class, one has to extend ReferenceManager instead when IR has to be opened on a specified IndexCommit.

Contributor guide
Research direction
Start by reading ReaderManager, ReferenceManager, and IndexCommit to understand how readers are currently opened and why a specified commit is unsupported. Identify the existing ReaderManager construction entry points and determine the API shape needed to open it on a given IndexCommit. Done means callers can create a ReaderManager for the specified commit without extending ReferenceManager.
