Preserve django_site table during e2e db clearing to
avoid breaking site configuration. Add video recording
on first retry and screenshot capture on failure for
easier debugging of flaky tests.
We want to be able to quickly start a local isolated env for the
e2e testing, we don't want to share to same db with the classic
dev env because the e2e db should be empty before tests execution.
And we don't want to clear our dev db every time. Also provide a new
makefile handy command to launch the e2e env and the tests in one
command, great.
