✨Frontend: Dynamic input ports

[odeimaiz]

What do these changes do?

This PR implements a feature that will give users the impression of having dynamic number of inputs (only when it comes to data inputs).

In order to have this feature enabled, the service needs to provide minVisibleInputs info. From here on, the frontend and user will play with the number of visibible of the inputs. When instantiating a service, the minVisibleInputs will be shown, then the user can press the plus button to show more, the plus button will disappear when we reach the maximum number of inputs. Also if the last input gets populated, one more will automatically show up.

Demo with minVisibleInputs=2:

Cool!

I have some questions

1. this feature was only for file ports, right?
2. If so, how ports are shown if a service has its ports mixed: e.g. int, file, float, file, bool, file, file, file, bool.
3. minVisibleInputs is a new attribute in the service input. Can you like the PR to the change in the backend?
4. this value is set at the service metadata, right? i.e. for the example above you released a new version of plot2D

looks cool!

Very very cool!
A have a similar question to PC's one: does minVisibleInputs have to be in the service metadata? Does is work like boot-options?

After this one is merged I will have a followup PR for the backend to add support for this.

Correct, as mentioned in the PR description only data inputs

2. If so, how ports are shown if a service has its ports mixed: e.g. int, file, float, file, bool, file, file, file, bool.

I'm expecting the "dynamic" data inputs to go last in the inputs list

3. minVisibleInputs is a new attribute in the service input. Can you like the PR to the change in the backend?
4. this value is set at the service metadata, right? i.e. for the example above you released a new version of plot2D

Yes it is needed.
