Add common methods to the BaseControlTask to reduce boilerplate in Tasks

It feels like I've seen these implementation classes in tests before.

If ControlTask is a protocol, perhaps BaseControlTask should implement common methods and subclasses should override.

For example, how many ways are there to implemement def name? I've looked at every single one, and all of them (except for one test one) implement it as:

    @property
    def name(self) -> str:
        return self._name

That suggests it should be part of BaseControlTask, and probably many other methods should be as well.

But generally, if the setup for a test is long, that suggests the API is bad.
