Description
It would be good to be able to uniquely identify LeafReaderContext objects associated within a single IndexSearcher. This would allow storing of metadata around segments, such as demonstrated in #1954
The ID will be unique across the IndexSearcher instance and will make no guarantees of any semantic value outside the instance.

Contributor guide
Research direction
Start by reading the LeafReaderContext and IndexSearcher APIs, then review the metadata use case referenced in #1954. Done means each LeafReaderContext associated with one IndexSearcher has a unique ID, with no uniqueness guarantee outside that IndexSearcher.
