IMPALA-10713: Use PARTITION-level locking for static partition INSERTs for ACID tables
Currently Impala always creates TABLE-level locks for INSERTs
for ACID tables. With this patch static partition INSERTs take
PARTITION-level locks only.
Testing:
* extended ACID stress test with partitioned INSERTs
