Add `name` parameter to a `SharedMemoryManager.ShareableList` method

Feature or enhancement

I would like to pass a name for shared list from SharedMemoryManager but I apparently cannot do this.

with SharedMemoryManager() as smm:
    my_shared_list = smm.ShareableList(sequence=range(10),name="special name")
    pass

What I get:

my_shared_list = smm.ShareableList(sequence=range(10),name="special name")
TypeError: SharedMemoryManager.ShareableList() got an unexpected keyword argument 'name'

Possible solution

Just change method ShareableList in the bottom of this source file to following:

        def ShareableList(self, sequence, name=None):
            """Returns a new ShareableList instance populated with the values
            from the input sequence, to be tracked by the manager."""
            with self._Client(self._address, authkey=self._authkey) as conn:
                sl = shared_memory.ShareableList(sequence=sequence,name=name)
                try:
                    dispatch(conn, None, 'track_segment', (sl.shm.name,))
                except BaseException as e:
                    sl.shm.unlink()
                    raise e
            return sl

I wonder

Why this feature is not implemented from the very beggining?

Start in Lib/multiprocessing/managers.py at the SharedMemoryManager.ShareableList method near the bottom of the file, then compare it with shared_memory.ShareableList's name parameter. Done means the manager method accepts and forwards name while retaining its tracking and cleanup behavior.
