auto-t: added autotest for FT over SAE This test was copied from testFT-PSK-roam, but for SAE. The test behaves as follows: - Connect to SAE network (full authentication) - Fast transition to another SAE AP - Fast transition to a PSK/WPA2 AP

auto-t: prepare autotests for test-runner re-write The tests basically remained the same with a few minor changes. The wiphy_map and in turn hostapd_map are no longer used. This was already partially converted a long time ago when the 'config' parameter was added to HostapdCLI. This patch fully converts all autotests to use 'config' rather than looking up by interface. Some test scripts were named 'test.py' which was fine before but the new rewrite actually loads each python test as a module. The name 'test' is too ambiguous and causes issues due to a native python module with the same name. All of these files were renamed to 'connection_test.py'.

auto-t: fix SAE FT test and update Updated testFT-SAE-roam to use the TestContext APIs as well as fixed the failure which was introduced after requiring stricter AKM logic for SAE networks. The new failure was due to the hostapd config not including the standard SAE AKM which is actually required by the spec.

auto-t: remove direct scan() call when possible All tests which could avoid calling scan() directly have been changed to use the 'full_scan' argument to get_ordered_network. This was done because of unreliable scanning behavior on slower systems, like VMs. If we get unlucky with the scheduler some beacons are not received in time and in turn scan results are missing. Using full_scan=True works around this issue by repeatedly scanning until the SSID is found.

auto-t: replace waiting for network with device Many tests waited on the network object 'connected' property after issuing a Connect command. This is not correct as 'connected' is set quite early in the connection process. The correct way of doing this is waiting for the device state to change to connected. This common code was replaced, hopefully putting to rest any random failures that happen occasionally.

# Check that iwd is on BSS 1 once out of roaming state and doesn't
# go through 'disconnected', 'autoconnect', 'connecting' in between
auto-t: update roaming tests with wait_for_object_change Every single roaming test had one of two problems with watching the state change between roaming --> connected. Either the test used wait_for_object_condition to wait for 'connected' which could allow other states in between. Or it simply used an assert. The assert wouldn't allow other state changes, but at the cost of potentially failing due to IWD not having made it to the 'connected' state yet. Now we have wait_for_object_change which takes two conditions: initial (from_str) and expected (to_str). This API will not allow any other conditions except these, and will wait for the expected condition before continuing. This allows roaming test to reliably wait for the roaming --> connected state change.
