> Extend shared scan optimizer to reuse computation from other operators

> Project: Hive

> Follow-up of the work in HIVE-16602.
> HIVE-16602 introduced an optimization that identifies scans on input tables
> that can be merged so the data is read only once.
> This extension to that rule allows to reuse the computation that is done in
> the work containing those scans. In particular, we traverse both parts of the
> plan upstream and reuse the operators if possible.
> Currently, the optimizer will not go beyond the output edge(s) of that work.
> Follow-up extensions might remove this limitation.
