iotcentral has duplicate x-ms-discriminator-value for TileConfiguration

[cataggar]

iotcentral package-2022-10-31-preview has duplicate "x-ms-discriminator-value": "command" inheriting from TileConfiguration. Based on the naming conventions, I think you may want to make the second "x-ms-discriminator-value": "commandTile".

    "CommandConfiguration": {
      "description": "Configuration specifying options for a command tile.",
      "x-ms-discriminator-value": "command",
      "allOf": [
        {
          "$ref": "#/definitions/TileConfiguration"
        }
      ],
      "type": "object",
      "properties": {
        "device": {
          "type": "string",
          "description": "The device id that the command is associated with"
        },
        "command": {
          "type": "string",
          "description": "The command id to associate the tile to"
        }
      },

    "CommandTileConfiguration": {
      "description": "Configuration specifying options for a command tile",
      "x-ms-discriminator-value": "command",
      "allOf": [
        {
          "$ref": "#/definitions/TileConfiguration"
        }
      ],
      "type": "object",
      "properties": {
        "group": {
          "description": "The ID of the device group to display",
          "type": "string"
        },
        "command": {
          "description": "The command to reference in the tile",
          "type": "string"
        },
        "device": {
          "description": "The device to reference in the tile"
        }
      },
      "required": [
        "group",
        "command",
        "device"
      ]
    },

I discovered this while working on Azure/azure-sdk-for-rust#1414.

This looks like it was added in #20981. cc @yang-hai-feng @heaths

I possible fix would be to update:

    "CommandTileConfiguration": {
      "description": "Configuration specifying options for a command tile",
      "x-ms-discriminator-value": "command",

to:

    "CommandTileConfiguration": {
      "description": "Configuration specifying options for a command tile",
      "x-ms-discriminator-value": "commandTile",

This would need to be updated in the backend as well.
