Code improvement in convert.py

Browse Source 
improve code reading and clarity of topology parser:
*modify the connections binding
=>def fiber_dest_from_source to find all dest_city connected to a source_city
=>def fiber_link to return the fiber link from source_city to dest_city
*makes the parser algorithm more understandable
*prepare for the equipment parser
