### Is your feature request related to a problem or challenge?
In our code / optimizers we have a lot of code that looks like this when we
are
trying to rewrite a SortExec node by making a copy and changing only some of
the
fields. For example:
```rust
new_plan = Ok(Arc::new(
SortExec::new(sort_exec.expr().to_vec(),
Arc::clone(sort_exec.input()))
.with_fetch(sort_exec.fetch())
.with_preserve_partitioning(true),
));
```
This is problematic and we have had bugs in the past when SortExec got a new
field (like `fetch`)
We would like to simply be able to make a copy and modify appropriately:
```rust
new_plan =
Ok(Arc::new(sort_exec.clone().with_preserve_partitioning(true)));
```
Many ExecutionPlans like [`ParquetExec` already implement
`Clone`](https://docs.rs/datafusion/latest/datafusion/datasource/physical_plan/parquet/struct.ParquetExec.html#impl-Clone-for-ParquetExec)
so it is nice to
make the rest consistent
### Describe the solution you'd like
I would like to derive `Clone` for other plans
