Improved machine location change map view + backend relaxation for new machines

[jannisborn]

• Machine location change map view now shows also the map view toggle thus supporting hybrid and satellite map (user request)
• New machines with incorrect address (>1km away) are no longer rejected since this may make it impossible to submit a new machine. Instead, it's a success but a warning is given to slack (AKA developer team) to verify the new machine
