    Handle duplicate/invalid entries in migration SSH inbound addresses

    An error (e.g a typo) in a custom tripleo-heat-templates environment
    file could lead to an invalid match block in /etc/ssh/sshd_config.
    SSH fails-safe and refuses all logins in this case.

    This change validates the migration_ssh_localaddrs parameter is an
    array of IP addresses and removes and duplicate entries.
