IMPALA-5137: Support Kudu UNIXTIME_MICROS as Impala TIMESTAMP Adds Impala support for TIMESTAMP types stored in Kudu. Impala stores TIMESTAMP values in 96-bits and has nanosecond precision. Kudu's timestamp is a 64-bit microsecond delta from the Unix epoch (called UNIXTIME_MICROS), so a conversion is necessary. When writing to Kudu, TIMESTAMP values in nanoseconds are averaged to the nearest microsecond. When reading from Kudu, the KuduScanner returns UNIXTIME_MICROS with 8bytes of padding so Impala can convert the value to a TimestampValue in-line and copy the entire row. Testing: Updated the functional_kudu schema to use TIMESTAMPs instead of converting to STRING, so this provides some decent coverage. Some BE tests were added, and some EE tests as well.
