tests: Add connecting-while-CSA tests

Add a few tests to validate what happens with connections
while an AP is doing CSA:
 - quiet to diff channel (shouldn't connect)
 - quiet to same channel (shouldn't connect)
 - non-quiet to diff channel (shouldn't connect)
 - non-quiet to same channel (should connect)
