ParkingLot Concurrency changes

Remove Synchronized from parkVehicle and unparkVehicle as it is not required

ParkingSpot has been modified to be thread safe.
Clients need not lock exclusively.
Number of floors wont change after construction. so no need for synchrnoziation there.

Changed concurrentHashMap to HashMap
there are no iterations happening on map, or there is no putIfAbsent kind of operations

hence use of concurrentHashMap is not needed.

Note: I am prepping for interviews, and i am reading JCIP, trying to implement the concepts here.
