[Tagging] Charging stations

[patata]

Currently socket:type1 and socket:type2 are not clarifying if the
station has a cable or we must bring our own.
Since the connector is not necessarily a socket, it is being discussed
on our telegram group https://t.me/openchargemap to change all sockets
into connector. Only add socket or cable where it needs to be
differentiated.

Examples :
connector:type1:socket
connector:type2:cable
connector:ccs
connector:chademo
