As we move on to introduce a DAG into Packer, we are introducing a Scheduler interface, as well as a first implementation of it which replicates the current scheduling algorithm, but centralises all the code related to evaluation and execution of components. This won't pass tests in the current state as only the logic has changed, and tests haven't been updated yet. This will come later in the refactoring process.
