IMPALA-7538: Support HDFS caching with LocalCatalog
This patch adds support for HDFS caching in LocalCatalog coordinators.
We use the same way catalogd propagates HdfsCachePools in catalog-v1.
They are cached in LocalCatalog coordinators as v1 and are not
“fetch-on-demand” since only cache pool names are cached.
The isMarkedCached markers of HdfsTable and HdfsPartition are also
propagated to the LocalCatalog coordinators for correctly handling
ShowTableStats and ShowPartitions statements with caching information.
Tests:
- Revive hdfs caching related tests in metadata/test_ddl.py and
query_test/test_hdfs_caching.py for LocalCatalog.
