cache file in the leaf level directories to support ConvertCountToDirectScan
optimization.

@vdiravka Yes, I have also observed that there are two places we store the
list of directories. I think we should keep the directories cache file as is
since it is used for checking timestamps. I think we can remove the directories
list from the Metadata Summary cache file. I will file a different jira for
that. Let me know if you have any other comments.

> Since the leaf level directory doesn't store the metadata directories file,
> while reading summary if the directories cache file is not present, it is
> assumed that the cache is possibly corrupt and reading of the summary cache
> file is skipped. Metadata directories cache file should be created at the
> leaf level.
