port mirror without Juniper header still requires analyzer IP address

[Tony Liu]

With 3.2.5.0-51, this mirror setting on port doesn't work. No mirror entry is created.

            "mirror_to": {
                "analyzer_name": "my-analyzer",
                "analyzer_mac_address": "02:46:5e:53:c8:4d",
                "juniper_header": false,
                "udp_port": null,
                "static_nh_header": null,
                "routing_instance": "default-domain:demo:analyzer:analyzer",
                "encapsulation": null,
                "nh_mode": "dynamic"
            }

To make it work, need to add analyzer_ip_address, any address is fine.

                "analyzer_ip_address": "192.168.34.25",

There must be some validation against analyzer_ip_address, and such validation should be removed for
the case of no-juniper-header.

Also, it would be good to implement L3 lookup based on analyzer IP address, instead of L2 lookup based
on analyzer MAC address.
