hive dist area questions

[Owen O'Malley]

Thejas,

    While uploading the new storage api 2.5.0 release into the dist area, I
realized that we had some non-releases in there. Thejas aded "ldap-fix" in
May 2015 and Sushanth added "hive-parent-auth-hook" in Jan 2016. Are they
releases? Are they out of date?

I also went through the dist area and replaced our old md5 to sha256, so
that we meet the new requirements for checksums.

Thanks,
   Owen
