The dateutil package uses lazy import to selectively expose its features: `parser`, `relativedelta`, `rrule`, `tz`. Depending on installed modules and order of initialization, there was no guarantee that a given feature was already loaded during the preparation of the action context. This patch ensures that we always preload the feature set we need, and only that feature set. This way we have a consistent `dateutil` lib in the action context at all times.
