Vuk Ercegovac ad265842b6 IMPALA-7702: enable fetch incremental stats by default

Flips the default from always off to always on for
--pull_incremental_statistics. With this setting, the default
is for coordinators to fetch incremental stats from catalogd
directly (only when computing incremental stats) instead of
receiving it from the statestore broadcast.

Fetching incremental stats is not applicable when using a
CatalogMetaProvider. By making fetch the default, it would
require that --pull_incremental_statistics is set to false
when enabling CatalogMetaProvider. This change makes
--use_local_catalog to take priority over --pull_incremental_statistics
so that when both are turned on, only the local catalog setting
is enabled.

Testing:
- manual testing
- moved the testing for pull incremental stats out of custom cluster
  tests since the default flipped
- added tests that run with local catalog and pulling incremental stats.
