Review Comment:
The policyChecked hacking the UnboundRelation, I can imagine that there will
be lots of fields need added.
How about generate a LogicalCheckPolicy in the LogicalPlanBuilder?
And then you can write a rule to generate a new filter to the
logicalRelation, like this:
```java
logicalCheckPolicy(logicalRelation()).thenApply(ctx ->
LogicalCheckPolicy<LogicalRelation> checkPolicy = ctx.root;
LogicalRelation relation = checkPolicy.child();
Optional<String> filter = checkPolicy.getFilter(relation);
if (filter.isEmpty()) {
return relation; // no any policy, so we remove the
LogicalCheckPolicy Plan
}
// has policy, we should remove LogicalCheckPolicy and add a filter to
relation
Expression filter = new NereidsParser().parseExpression(filter.get());
return new LogicalFilter(filter, relation);
)
```
