cells rpc API _handle_cell_delete regressed with commit 222d44532c65ddf3f26532ced217890628352536

[Matt Riedemann]

https://review.openstack.org/#/c/121800/ changes the cells RPC API in a non-backwards compatible way in the _handle_cell_delete method where method_name should be 'soft' or 'hard' but it's changed to 'soft_delete', 'delete' or 'force_delete'.

We need this reverted or fixed on master before we release kilo.

    Revert "Allow force-delete irrespective of VM task_state"

    This reverts commit 222d44532c65ddf3f26532ced217890628352536.

    It changed cells RPC messaging in an incompatible way, and is also
    more complicated than we want for a backport.

    Note that this includes a change to force_delete() which calls
    self._delete() directly so that we can pass the force_delete type
    in so that the notification is named properly (and thus passes
    the current tests which expect that to be the case).
