Add test_e2e_40_sdntrace.py::TestE2ESDNTrace::test_030_run_sdntrace_for_stored_flows to test how the traces are obtained from flow_manager stored_flow.
@viniarck, note that now the /traces endpoint is tested for 4 traces, two of them are the same, so only 3 are returned. Two of them correspond to a same switch and the other to another switch.
Fix #174
Add
test_e2e_40_sdntrace.py::TestE2ESDNTrace::test_030_run_sdntrace_for_stored_flows
to test how the traces are obtained from flow_manager stored_flow.Also,
test_e2e_40_sdntrace.py::TestE2ESDNTrace::test_001_run_sdntrace_cp
hass passed.
