Create new project from AzQueueTestTool Spike under Main solution

• Refactor code to decouple core logic to be reused by both "AzQueueTestTool" and Service Principal Test project
• Fix Test project linked dependencies
• Remove unnecessary functionality such as push messages to queues
• Tool's main purpose should be just to create or fix Service Principals and Users, making sure they do match preconditions required during Integration Testing
