    Fix test_keepalived_ipv6_support for Keepalived v1.2.20
    
    In commit [1] (some explanation in [2] ) VRRP initialisation is enhanced
    to read source IP address(to use when sending VRRP packets) from the
    HA interface or from keepalived config("unicast_src_ip" parameter).
    If it is unable to find IP address, VRRP initialisation will fail with
    error "Cannot find an IP address to use for interface".
    
    In the test, we set vrrp->family to AF_INET by setting vip to
    169.254.0.1/24 through config, but not providing source IPv4 address(i.e
    no 'unicast_src_ip' option or no IP on HA interface), making the test
    to fail with [1]. To fix that, we set the IP address on HA interface.
    
    Note: Commit [1] is added in Keepalived version 1.2.20.
    Tested the fix on both Keepalived v1.2.19 and Keepalived v1.2.20.

Title:
  Keepalived v1.3.5 failing to assign IP for HA interface

Status in neutron:
  Fix Released

Bug description:
  From the below syslog, I see keepalived is unable to read IP address
  from config filr to configure HA interface(though config file is
  properly configured). Need to check why this is happening. I also
  tested Keepalived v1.3.5 on ubuntu machine and saw the same error.

  
  Steps to reproduce:
  Install Keepalived v1.3.5 and run below functional test
  neutron.tests.functional.sanity.test_sanity.SanityTestCaseRoot.test_keepalived_ipv6_support 
  This test will fail and you can see the errors in syslog.
