      Description

      Currently Impala always create TABLE-level locks for INSERTs for ACID tables:

      https://github.com/apache/impala/blob/ced7b7d221cda30c65504e18082bb0af6c3cb595/fe/src/main/java/org/apache/impala/service/Frontend.java#L2153

      For static partition INSERTs we could create PARTITION-level locks instead.
