[PATCH v2 10/13] client: Add BasicServiceSets property to network

[James Prestwood <prestwoj@gmail.com>]

The property itself is an array of paths, but this is difficult
to fit nicely within a terminal. Instead just display the count
of BSS's. Displaying a detailed list of BSS's will be done via
a separate command.
