[NEMO-337] IRDAG Unit Tests (#195)

JIRA: NEMO-337: IRDAG Unit Tests

Major changes:
* IRDAGTest: Tests to ensure various combinations of IRDAG insert(), delete(), and setEP() method invocations pass/fail the integrity checker as expected
* IRDAGChecker: Aggregates all IRDAG EP/utility vertex integrity checking logic into a single place.

Minor changes to note:
* Removes IREdge property snapshot hacks
* Removes unused legacy code (e.g., PhysicalPlanGenerator#splitScheduleGroupByPullStageEdges)

Tests for the changes:
* Simple tests in IRDAGTest
* IRDAGTest#testThousandRandomConfigurations: Randomly generate and validates one thousand different (not necessarily unique) IRDAG configurations given a very simple three-vertex input IRDAG
