* add support for lifespan tasks
* allow passing args to lifespan task
* add message to the cancel call
* allow asynccontextmanager as lifespan tasks
* Fix integration.utils.SessionStorage
Previously the SessionStorage util was just looking in localStorage, but the
tests didn't catch it because they were asserting the token was not None,
rather than asserting it was truthy.
Fixed here, because I'm using this structure in the new lifespan test.
* If the lifespan task or context takes "app" parameter, pass the FastAPI instance.
* test_lifespan: end to end test for register_lifespan_task
* In py3.8, Task.cancel takes no args
* test_lifespan: use polling to make the test more robust
Fix CI failure
* Do not allow task_args for better composability

* typed mixins
* implicit mixin=True kwarg for ComponentState subclasses
* fix: always init other subclasses
* adjust tests: all mixins support base vars now
* [REF-2265] ComponentState: scaffold for copying State per Component instance
Define a base ComponentState which can be used to easily create copies of the
given State definition (Vars and EventHandlers) that are tied to a particular
instance of a Component (returned by get_component)
* Define `State` field on `Component` for typing compatibility.
This is an Optional field of Type[State] and is populated by ComponentState.
* Add integration/test_component_state.py
Create two independent counters and increment them separately
* Add unit test for ComponentState
