[improve]: Stop Workflow Flow Component should expose condition

### Improvement target

Stop Workflow Component

### Improvement description

Stop workflow component is usually used with condition flow component.

It takes 2 branches one for breaking path and another for executing process. As break workflow branch contains only Brea Workflow the rest of branch is empty and represented as straight line.
It would be better to introduce property for definition of breaking conndition.
Component can have title like Break Workflow On/If/When
Workflow graph itself will be tidy and more narrow.

### Observed Version

0.2.3
