autotest: Refactor reusable WiFi test base logic
Break WiFiTestBase into WiFiTestBase and WiFiCellTestBase. The former
contains bits we'd like to share with Chaos tests, and the latter is
specific to tests run in WiFi cells with the traditional
DUT/router/server trio.
TEST=Ran:
./run_remote_tests.sh --remote=chromeos1-shelf1-host4 \
check_bintval check_dtimperiod check_ps check_rxfrag check11b
This should check that all consumers of the existing test base were
updated and are working.
