rescue_instance RPC has reverted to passing a dict

[Phil Day]

Change https://review.openstack.org/#/c/62314/ mistakenly made the conversion of the instance object in compute/rpcapi.py rescue_image() unconditional on the RPC version. From 3.9 onwards this should be passed as an object

    Fix error in rescue rpcapi that prevents sending objects

    The change restores the rescue_instance rpc's ability to send
    instance objects from version 3.11 onwards, that was inadvertently
    broken by https://review.openstack.org/#/c/62314

    Unit test modified to check that rpc version passes instance object
    instead of dict.
