feat/GWW-133: Add tooltip to layer options on map

[lsarni]

Ticket: GWW-133

Main feature:

• Add tooltip to the zoomable layers on the map with explanation
• Tooltip open/closes when clicking on the info icon button

The security hotspot is not a problem because we are the ones defining the HTML that gets rendered
