If implemented, will provide users with a way to cache index files.
This addresses issues where the index file is loaded and unmarshalled in
concurrent reconciliation resulting in a heavy memory footprint.
The caching strategy used is cache aside, and the cache is a k/v store
with expiration.
The cache number of entries and ttl for entries are configurable.
The cache is optional and is disabled by default
