Fixed Issues in Kudu

This section lists the issues that have been fixed since the previous version.

KuduPredicate class in Java client does not handle Date columns: Apache JIRA: KUDU-3152Summary:
Prior to this fix, if you had a table with DATE column, you could not scan for it using the java client. A check for minimum and maximum boundaries of integer representation of java.sql.Date was added to match MIN_DATE_VALUE and MAX_DATE_VALUE in DateUtil.
