[PATCH 3/5] ap: add SSID property

[James Prestwood <prestwoj@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 2093 bytes --]

Its useful being able to refer to the SSID once an AP is
started. For example opening an iwctl session with an
already started AP provides no way of obtaining the SSID.
