Title: PDI-3971 add local cache to ZIP & TAR file systems

VFS indexes all files inside zip and tar files but keeps the index in the
weak/soft references based cache - so indexed files can be GC'ed and lost. It causes intermittent issues with zip files. I added local strong reference based caches to avoid it.
