Add ability to show tooltips for buttons

[marinaxkonsta]

To be able to have a tooltip show on hover to explain what the button does.

Changes:

• Using react-popper-tooltip to show the tooltip
• Pass in the popper options through the widget config ie. widgets={[CustomWidgetconfig({popper: {name: "test", placement: "left", offset: [15,25]}}]}
