  - Merge "fix netapp delete_share private_storage cleanup"
  - fix netapp delete_share private_storage cleanup

    The NetApp driver records info [original_name] and
    [original_junction_path] when a share is managed.This data
    is not removed during share deletion and is stored in
    private_storage and never cleaned up

    This change ensures that when a NetApp share is managed, the
    associated private storage entry is deleted via
    private_storage.delete(share['id'])

    If the share does not exist, no deletion of private storage is done
    so that diagnosis is possible if necessary.

    private_storage.delete(share['id]) also removed from
    _update_create_from_snapshot_status as it now introduces redundancy for
    the deletion there, since the _delete_share function is already being
    called before that.

    Test Plan:

    test_delete_share_clears_private_storage
    - Verifies private storage is deleted when the share exists.
    This is when _share_exists() is True

    test_delete_share_nonexistent_does_not_delete_private_storage
    - Verifies that when _share_exixts() returns False,
    private_storage.delete is not called, preserving any metadata.
