Reusable Execution Context (#792)

* It removes all programmatically created instances of ExecutionContext in main code.
* The ExecutionContext is now a Spring bean with @ExecutionScope
* execution scope and ends with a successful recipe run
* TestProjectContext uses Spring and components scan now to create the ProjectConetxtInitializer
* A new test helper ActionTest was created which allows testing actions that require the ExecutionContext that is now created together with beans to create a ProjectConetxtInitializer instance
* The execution times of tests might have become even worse as potential too many beans are created when org.springframework.sbm is scanned
* An ArchUnit test was introduced to flag invalid instance creations of any class implementing ExecutionContext.
