Adds a `features` app with a swappable waffle Flag (WAFFLE_FLAG_MODEL) that gains a m2m to Club, so a feature can be rolled out club by club. Two things worth calling out: - `everyone` keeps waffle's contract of overriding *all* other targeting, so club targeting is only consulted when `everyone is None`. This keeps `everyone = False` usable as a hard kill-switch. - m2m edits don't call save(), so waffle's per-flag cache would go stale when clubs are added or removed. A m2m_changed receiver flushes it from both directions, and get_flush_keys() drops the club-set key alongside waffle's own. Note for future flag tests: waffle's cache is not rolled back with the test transaction, so tests touching flags must clear it (see features/tests.py).
