[Autotest failure] network_WiFi_BSSTMReq has over 40% failure rate

Project Member Reported by harpreet@chromium.org, May 18 2018

Issue description

Newly added network_WiFi_BSSTMReq test has very high failure rate. See link below.

Most failures are due to "Failed to roam" error while few others are due to "Autotest client terminated unexpectedly: DUT is pingable, SSHable and did NOT restart un-expectedly. We probably lost connectivity during the test., client.bin.job.__init__ failed: [Errno 28] No space left on device"

Also, please remove this test from the following suites:

suite:wifi_endtoend
suite:wifi_release

network_WiFi_BSSTMReq: move to wifi_flaky

This test is failing in wifi test suites. Move to wifi_flaky while we resolve this.

network_WiFi_BSSTMReq: Fix test failures

Many of the network_WiFi_BSSTMReq test failures are caused be either (a) the AP not
supporting BSS Transition Management, or (b) the driver picking the original AP to
roam to instead of the one suggested by the BSS Transition Management Request (this
is possibly because the driver prefers the 5GHz band).

To fix (a), I checked for the output of the request ('OK' indicates that it is
supported and was successfully sent) and raised a TestNAError if 'OK' was not found.

To fix (b), I switched the two APs so that the client would instead be roaming from
2.4GHz band to 5GHz band.

BUG= chromium:844762 
TEST=Ran on machines that failed these tests (e.g. chromeos2-row11-rack4-host2 and
     chromeos2-row11-rack7-host6) and they now pass.
