InfluxDB 2.0: Label schema has to have defined properties as dictionary [area/api]

[bednar]

The Label schema has defined properties as:

Key/Value pairs associated with this label. Keys can be removed by sending an update with an empty value.

but there is missing additionalProperties as is specified in OpenAPI 3 specification for dictionaries. The Label schema has to be defined in this way:

Label:
      type: object
      properties:
        id:
          readOnly: true
          type: string
        name:
          type: string
        properties:
          type: object
          additionalProperties:
            type: string
          description: Key/Value pairs associated with this label. Keys can be removed by sending an update with an empty value.
          example: {"color": "ffb3b3", "description": "this is a description"}
