Add name keyword argument to loop.create_task()

[fantix]

• Fixes BUG: uvloop.loop.create_task() is missing 'name' parameter #309.
• Refs bpo-34270.

Does this gain us something over the slightly more readable:

try:
    task.set_name(name)
except AttributeError:
    pass

[1st1]

It won't mask an AttributeError coming from the set_name implementation. Which is unlikely but can still happen especially with custom task factories.

Thanks for the suggestion and comments!

I would write something like this:

if name is not None and hasattr(task, "set_name"):
    task.set_name(name)

But this is getting into details (try..except overhead? Two O(1) operations?) and stepping away from the copied code, so I think I'll merge as it is now.
