Change subject: IMPALA-7867 (Part 3): ArrayList cleanup in planner ...................................................................... IMPALA-7867 (Part 3): ArrayList cleanup in planner Continues the work to tidy up uses of ArrayList, HashMap and HashSet, this time in the planner package and its dependencies. Changed the code to follow standard Java practice: use base interfaces for method and variable declarations, specific subclasses when creating objects. Replaced trivial uses of Guava newFoo() methods with direct object creation such as new ArrayList<>() as recommended by Guava. Fixed trivial warnings such as unused imports and missing @Override. Removed constuctor type parameters when the compiler can infer them. Testing: this is a pure source change, no functional changes. Ran the pre-review tests to verify no regressions.
