[SOLR-9269] Refactor the snapshot cleanup mechanism to rely on Lucene
The current snapshot cleanup mechanism is based on reference counting
the index files shared between multiple segments. Since this mechanism
completely skips the Lucene APIs, it is not portable (e.g. it doesn't
work on 4.10.x version).
This patch provides an alternate implementation which relies exclusively
on Lucene IndexWriter (+ IndexDeletionPolicy) for cleanup.
