    Raise ApiError in response to InstanceTypeNotFound

     * Updates methods in nova.compute.instance_types to catch
       InstanceTypeNotFound exceptions and re-raise them as ApiError.
       - Previously, the methods in instance_types were raising ApiError in
         response to DBError, but the underlying db calls have since been
         updated to detect empty results and throw more specific exceptions.
     * Updates get_instance_type_by_flavor_id to not try to catch DBError,
       as the underlying db call only ever raises FlavorNotFound.
       get_instance_type_by_flavor_id should not raise ApiError, as callers
       expect the FlavorNotFound exception and know how to handle it.
     * Fixes bug 872618
