Review comment:
When the logical plan is built from the AST and `HiveTableScans` are
instantiated table properties defined in the AST are lost.
When the optimized logical plan is converted back to AST only properties
coming from Druid and JDBC scans are populated. We could add additional
properties from `HiveTableScans` in the same way.
I think passing `acid.fetch.deleted.rows` as a table property in the query
is a good idea and we can benefit from it when building an Incremental MV
rebuild plan. I will try to include this into
