Testcase 3 Apex compatibility fixes
- Workaround a bug releng in getting opedaylight nodes - Add some sudo commands because the path is not properly set otherwise it seems - remove needless command that gets ip information from the compute, since that is already available from when the command was ran on the controller - Handle attaching the quagga instance to Apex's br-ex ovs bridge Change-Id: I870f1049d9cce696ec26376a09db5f9e9bac0bf9 Signed-off-by: Romanos Skiadas <rski@intracom-telecom.com>
