Refactor SFC testcase
- Change the way the test checks if the vxlan_tool has started.
Now the vxlan_tool is detected even if another python process is up.
- Log the exceptions in the vxlan_tool check block. The exceptions that
occur are not destructive for the testcase but it's better to be
visible.
- Add a 60 seconds sleep before the testcase starts to give plenty of
time to ODL to add the correct flows.
- Move the testcase success/fail check blocks inside the try blocks.
The checks are performed on the stdout variable which is in scope
only inside the try blocks.
