core: update device 'metered' property on connection state change

Browse source 
The metered property of a NMDevice that reaches the activated state is
copied from the active connection and if its value is 'unknown' some
heuristics are used to guess the actual value.

When the connection is torn down the metered property is reset to
'unknown'.
