[MSHARED-640] Upgrade maven-invoker-plugin to resolve IT failure on Windows

Fix failing IT on Windows. The current parent Apache POM defines version 2.0.0 for the maven-invoker-plugin, where the issue due to the rename of mvn.bat on Windows with Maven 3.3.1 is fixed. The project should inherit from it instead of forcing version 1.7.
