Bug
1719632 [wpt PR 29606] - Use container elements to switch frames for testdriver rather than indices, a=testonly
Automatic update from web-platform-tests
Use container elements to select frames for testdriver switch_to_frame
The previous setup used two execute_script calls and the length of
window.frames to iterate over child crosing contexts. This failed if
an iframe was removed in a way that races with the click. Element
identifiers should be more stable since they are unaffected by other
DOM manipulation.

Change webdriver imports in executorwebdriver
I'm actually unsure if this was working correctly before; the use of
client.WebDriverException and subclasses doesn't look like it ought to
work given client.py doesn't import those.
