Description

IMPALA-7530 added retries in case LocalCatalog throws InconsistentMetadataFetchException. These retries apply to all code paths taking Frontend#createExecRequest().

"show partitions" additionally takes {{Frontend#getTableStats()} and aborts the first time it sees InconsistentMetadataFetchException.

We need to make sure all the queries (especially DDLs) retry if they hit this exception.
