Add cardinality estimate to AbstractPlan object #1475

Closed GustavoAngulo closed 6 years ago

GustavoAngulo commented 6 years ago

This PR adds the optimizer's cardinality estimate to the AbstractPlan object for use during plan execution. Includes test cases to verify it works. This is part of #1467 to add more optimizer estimates to plans.

Additionally, this PR adds an optimizer_test_util class with useful helper functions for creating test tables and generating plans. Future and possibly existing test cases should inherit from this class.
