First step to remove the re-aggregation for Continuous Aggregates is to remove the `chunk_id` from the materialization hypertable. Also added new metadata column named `finalized` to `continuous_cagg` catalog table in order to store information about the new following finalized version of Continuous Aggregates that will not need the partials anymore. This flag is important to maintain backward compatibility with previous Continuous Aggregate implementation that requires the `chunk_id` to refresh data properly.
