IMPALA-6386: Invalidate metadata at table level for dataload

Dataload currently executes bin/load-data.py for TPC-H,
TPC-DS, and functional-query concurrently. One of the final
steps for bin/load-data.py is to run a global "invalidate
metadata". Global "invalidate metadata" commands are known
to cause problem on concurrent systems. See IMPALA-5087.
For dataload, if TPC-H executes "invalidate metadata" while
TPC-DS is still creating tables and adding partitions,
the TPC-DS executor might erroneously believe that a table
does not exist.

This changes dataload to invalidate metadata at an
individual table level rather than globally. This
prevents the concurrency issue.
