[wifi interop lab] Get interop lab up and going
Wifi interop lab will allow for testing ChromeOS DUTs against 50+
commercially sold APs across different channels/frequencies. All the APs
are statically configured and this configuration is reflected in
chaos_ap_list.conf.
Due to the time it takes to test a given DUT against all APs (~3hrs) and
the fact that we can only run the test on 1 DUT at a time (due to
current design limitations), the plan is to split the test runs across
different days such that the test(s) will be run on each DUT once per
week.

We also plan to continue adding newer APs to the interop lab as needed.

TEST=Tested using kevin against all APs in chaos lab; unit tests (e.g.,
`utils/unittest_suite.py -r server/cros/ap_configurators/`)
