DPP2: Connection status result (Configurator)

Browse source 
A new argument to the DPP_AUTH_INIT command (conn_status=1) can now be
used to set Configurator to request a station Enrollee to report
connection result after a successfully completed provisioning step. If
the peer supports this, the DPP-CONF-SENT event indicates this with a
new argument (wait_conn_status=1) and the Configurator remains waiting
for the connection result for up to 16 seconds.

Once the Enrollee reports the result, a new DPP-CONN-STATUS-RESULT event
is generated with arguments result, ssid, and channel_list indicating
what the Enrollee reported. result=0 means success while non-zero codes
are for various error cases as specified in the DPP tech spec. If no
report is received from the Enrollee, the event with "timeout" argument
is generated locally.
