Logical Architecture: Enable connections to be optional
It shall be possible to make connections in the logical architecture optional.
This also requires a solution to connect multiple channels to one port and a check that such multiple inputs in 150% models are always corect (i.e. mutually exclusive).
This might require #4240 (closed)
Test instructions:
- Open an arbitrary project
- Ensure, that is contains a non-empty feature model
- Open the component architecture
- Select any channel
- Observe: The property section contains an entry for a presence condition
- Enter any valid or invalid presence condition
- Save the model
- Observe: The presence condition was saved for the channel
