In this patch a new unimodal optimizing strategy is introduced. The dags are executed in parallel via a memory aware node scheduler and executor.
The scheduler tracks the dependencies between the nodes and records the memory used by the system in order to run new nodes that fit these memory limits. Every representation needs to provide a memory estimate so the scheduler knows which representation nodes can be scheduled. The memory estimates consist of a cpu and gpu estimate and the scheduler is aware of both those attributes.
(The hyperparameter tuner and multimodal optimizer still need to be adapted to this new approach, therefore the tests are currently disabled)
