Async await code checker

[tusmester]

Create a tool that is able to discover async operations in source code and find issues. Create user stories for individual issues!

• async operations called without await
• async operations called without ConfigureAwait(false)
• async operations called with Wait() or Result
• find async candidates by collecting GetAwaiter().GetResult() calls
• async operations without CancellationToken parameter
• async operations that do not use the provided CancellationToken parameter.
