Catch InstanceNotFound exceptions for V2 API instance_actions

Use the common.get_instance method to get the instance object
in the V2 API instance_actions extension rather than call
the compute api directly. The utility function
handes InstanceNotFound exceptions and tranlsates them to HTTPNotFound
rather than letting them propagate up causing a traceback.
