UnboundLocalError: local variables referenced before assignment in integration tests

[Anastasia Kuznetsova]

During integration tests if stack or one of resources wasn't created before timeout expiration, then appropriate exception has to be raised:

message = ('Resource %s failed to reach %s status within '
                   'the required time (%s s).' %
                   (res.resource_name, status, build_timeout))
or

message = ('Stack %s failed to reach %s status within '
                   'the required time (%s s).' %
                   (stack.stack_name, status, build_timeout))

in /heat_integrationtests/common/test.py

Problem is that "res" and "stack" are local variables and can't be used outside 'while' loop.

    Fix variables reference in the integration tests methods

    In the common integration tests methods: _wait_for_stack_status and
    _wait_for_resource_status local variables 'res' and 'stack' were used
    outside the loop where they were referenced.
