InfluxDB 2.0: The "orgID" parameter shouldn't be required for "GET /labels" [area/api]

[bednar]

The GET /labels is defined as:

/labels:
    get:
      tags:
        - Labels
      summary: Get all labels
      parameters:
          - $ref: '#/components/parameters/TraceSpan'
          - in: query
            name: orgID
            description: specifies the organization of the resource
            required: true
            schema:
              type: string
      responses:
        '200':
          description: all labels
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/LabelsResponse"
        default:
          description: unexpected error
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Error"

but the orgID parameter is not required by an implementation:

-> GET
-> http://127.0.0.1:9999/api/v2/labels

<- 200 
<- OK
<- {
	"links": {
		"self": "/api/v2/labels"
	},
	"labels": [{
		"id": "03b441dfd9371000",
		"orgID": "03b440ac89b71000",
		"name": "Cool Resource1555332471625-IT"
	}]
}
