IMPALA-14695: Avoid some InconsistentMetadataFetchException
The patch tries to avoid InconsistentMetadataFetchException by:
1. prepopulating partition list/column stat in cache on first
GetPartialCatalogObjectRequest
2. accepting partitions if the table has changed, but the
received partition ids are the same as the requested ones
3. storing partitions in cache even if the response in not
consistent with the request
See the Jira for the script with parallel alter partitions
statements. With the patch this doesn't lead to
InconsistentMetadataFetchException and planning retries
anymore.
An alternative implementation for 1 would have been to remove
loadPartitionList and loadTableColumnStatistics completely.
Currently all tables load these eagerly, so the functions
are not useful.
