Layout v2

This PR is a step to refactor the layout language on Daiquiri.

This aim to rework the main structure. I think it is better to rename the properties with another PR.

Main yaml layout changed:

• component was removed and merged as type
• option dictionary was removed (the content was dropped directly inside the layout component)
  • type from parameterlist was renamed paramtype to avoid overlapping
• contents was renamed into children
• hardware component type was renamed into hardwaregroup
• hardware component type is now used for a single hardware widget

Main architecture changes:

• namespace helper was converted to typescript
• The whole layout connect component was converted to typescript
• Each component which can be part of the layout have now an dedicated file for the yaml validation (components/yaml-layout/components)
• Improve the user feedback when the layout is wrong
