can these be static members of WebrtcTestBase?

Done.

WebRtcTestBase or WebRTCTestBase.  It seems we use both WebRTC and WebRtc under
content/ so please just pick the one that's more common.

Hm. For the tests we are currently using Webrtc, like WebrtcBrowserTest. We
could change that, but then we need to update the gtest filters on the bots for
instance. I suggest doing this in a later CL and keep this one consistent with
the tests.
