client: Print IP Addresses / hint about netconfig

Browse Source 
When station 'show' is invoked, parse and print any IP addresses
associated with the interface.

If iwd network configuration is disabled and no IP addresses were
configured, print a hint to the user that a DHCP client might need to be
configured.
