feat: Allow custom controls to add one or more Option based attributes

[lucasnetau]

Allow adding Option attributes to custom controls (or when a template overrides a builtin control)

This can be defined by assigning the type: options

noSelect: flag can be set to true to hide the radio select buttons (where selecting options isn't used by the control).

Example definition:

columns: {
  label: 'Columns',
      type: 'options',
      values: [
      {
          "label": "Default Column",
          "value": "col1",
          "selected": false
      }
  ],
      noSelect: true,
},   

@todo: Support a no-value option

@kevinchappell WIP for the options code. Would like you opinion on the flag noSelect (default false) to disable the radio buttons, this could also be worded as allowSelection (default true)

oops, i never finished my review. this mostly looks good to me. i will take a swing at fixing the test and it should be good to merge after.

I have one more change to push to this. A button to switch from option => value to just an option (and value is equal to option). Useful for lists.

Restoring state in formBuilder for this attribute type currently needs to be implemented
