WIP IMPALA-14695: load partition list and column stats with table

The patch tries to avoid InconsistentMetadataFetchException by:
- prepopulate partition list/column stat in cache on first
  etPartialCatalogObjectRequest
- accept partitions if the table has changed, but the
  received partition ids are the same as the requested ones

See the Jira for the script with parallel alter partitions
statements. With the the test this doesn't lead to
InconsistentMetadataFetchException and planning retries
anymore.

TODO:
- loadPartitionList and loadTableColumnStatistics could
be removed completely - currently all tables load these
eagerly
