    Enable dns_domain_ports extension by default

    'dns_domain_ports' extension allows dns_domain to be set
    for ports and ML2 OVN supports it since wallaby[1]
    and ML2 OVS long before that.
    This patch replaces 'dns' with 'dns_domain_ports' for
    NeutronPluginExtensions in ml2 plugin heat template and
    all environment files.
    'dns' extension not equired to be enabled explicitly
    with 'dns_domain_ports' as it inherits all the capabilities
    of 'dns' extension.
