Fix most end-to-end issues with testcase 3 and reenable it
- Make the test work end-to-end on Fuel - Use the instance log to verify quagga started - Don't attempt to check for peering, as that is for a future release - Use the external IP of the controller for peering - Fix not getting the output of OpenDaylight commands Change-Id: Ia7bb533ab65e0fca6b7f48bb64133f6d8f3ff8ae JIRA: SDNVPN-114 Signed-off-by: Romanos Skiadas <rski@intracom-telecom.com>
