[YANG]: Add Yang model support for Multi ASIC port and device_metadata

[xincunli-sonic]

Why I did it

Cherry pick from public repo: sonic-buildiamge:

1. [YANG]: Add Yang model support for Multi ASIC port and device_metadata
2. Rename the leaf nodes to lower case.

In Multi ASIC scenario,

1. PORT configuration table requires core_id, core_port_id and num_voq:

{
    "PORT": {
        "Ethernet0": {
            "index": "0",
            "lanes": "101,102",
            "description": "fortyGigE1/1/1",
            "mtu": "9100",
            "alias": "fortyGigE1/1/1",
            "speed": "40000",
            "link_training": "off",
            "laser_freq": "191300",
            "tx_power": "-27.3",
            "coreId": "1",
            "corePortId": "1",
            "numVoq": "8"
        },
        "Ethernet1": {
            "index": "1",
            "lanes": "103,104",
            "description": "fortyGigE1/1/2",
            "mtu": "9100",
            "alias": "fortyGigE1/1/2",
            "admin_status": "up",
            "speed": "40000",
            "link_training": "on",
            "laser_freq": "191300",
            "tx_power": "-27.3",
            "coreId": "0",
            "corePortId": "14",
            "numVoq": "8"
        },
        "Ethernet63": {
            "index": "63",
            "lanes": "87,88",
            "description": "fortyGigE1/4/16",
            "mtu": "9100",
            "alias": "fortyGigE1/4/16",
            "speed": "40000",
            "laser_freq": "191300",
            "tx_power": "-27.3",
            "coreId": "0",
            "corePortId": "15",
            "numVoq": "8"
        }
    }
}

2. DEVICE_METADATA configuration table requires asic_id:

{
"DEVICE_METADATA": {
        "localhost": {
        "asic_id": "06:00.0",
        "asic_name": "asic0",
        "hwsku": "Force10-S6100",
        "default_bgp_status": "up",
        "docker_routing_config_mode": "unified",
        "hostname": "sonic-s6100-01",
        "platform": "x86_64-dell_s6100_c2538-r0",
        "mac": "4c:76:25:f4:70:82",
        "default_pfcwd_status": "disable",
        "bgp_asn": "65100",
        "deployment_id": "1",
        "type": "ToRRouter",
        "bgp_adv_lo_prefix_as_128" : "true",
        "buffer_model": "traditional",
        "yang_config_validation": "disable",
        "rack_mgmt_map": "dummy_value",
        "timezome": "Europe/Kiev"
    }
  }
}

Work item tracking

• Microsoft ADO (number only): 27252814, 27253157

How I did it

1. Added core_id, core_port_id and num_voq field to CONFIG_DB PORT table.
2. Added asic_id field to CONFIG_DB DEVICE_METADATA table.

We should not combine two PRs into one. We should have raised two separate PRs instead of just one. This way if something went wrong we have finer way to revert/fix the issue.
For this time I will allow it... but please don't combine PRs next time. @xincunli-sonic .
