NestedCheckbox component improvement for Feature Filter UI

[Alessandro100]

Improvements

• Add debounce option to trigger output of checkbox selection. This would allow the user to select many checkboxes without waiting for a search call every time. If after 400**ms there is no more options selected, output the checkbox change, which would trigger a search call to backend
• Continue the implementation of the nested checkbox recursion. Currently the nestedcheckbox component only supports 2 levels of checkboxes, but the datastructure could allow as many as we want
• Setup a way to have disabled states
