Code Issues Proposed changes

Remove legacy RequestSpec compat from conductor rebuild_instance 

Change I34ffaf285718059b55f90e812b57f1e11d566c6f made the
RequestSpec lookup required in the API, so we should not get
to conductor's rebuild_instance() method without a request spec
so this change removes the compat code from that method.

Related to blueprint request-spec-use-by-compute
