add new codec change and partition by to Clickhouse Executions table

[luluz66]

Note: These changes won't be auto migrated. I will create a new table with the
parition clause and columns with codec changes and then backfill.

1. For codec changes, I added ZSTD(1) to most of the columns, except for some uuid columns that didn't
   show much storage savings in dev testings and LowCardinality(String) columns.
2. Use LowCardinality for enum-like types.
3. change execution_id to execution_uuid in order by change.
4. Add a partition by clause
