Let's move more stuff into this class and make a FakeCWS (similar to FakeGaia)
out of it.

Things such as setup switches::kAppsGalleryURL,
switches::kAppsGalleryDownloadURL and switches::kAppsGalleryUpdateURL could all
be moved here. We need the test server's url to initialize them. This can be
done by passing the test server's url when it is available. 

Test suite class is better to have a FakeCWS as its member instead of deriving
from it.

Done.
