  Changed paths:
    M ovn/northd/ovn-northd.c
    M ovn/utilities/ovn-nbctl.c
    M tests/ovn.at

  Log Message:
  ovn: Detect and prevent duplicate address assignments.

This patch alters the 'ovn-nbctl lsp-set-addresses' command to check if
the IP addresses being added are duplicates of already-set IP addresses.
Test cases have been added for this detection.

This patch also adds a warning message to ovn-northd if duplicate IPv4
addresses are detected on a switch.
