[Snake and ladder]: Added handling for game go routines

[vnkdj5]

What?
The current go snake and ladder program does not wait for all games to finish.
Added waitgroups so that we wait for all the same to finish before closing the program.
Added Auto generating Ids for game so that we can track the moves of the game.
