Description

Scheduling for Kudu works the same way for HDFS and Kudu, however our docs pages don't mention the latter: https://impala.apache.org/docs/build/html/topics/impala_schedule_random_replica.html

We should add Kudu to the docs for the SCHEDULE_RANDOM_REPLICA query option and the RANDOM_REPLICA hint.
