Swagger definitions missing error codes/schemas under responses

[clintyoshimura]

The swagger definitions don't seem to have error codes/schema definitions. For example, PacketAnalyzers POST doesn't include the 400 error in the list of responses:

post:
  tags:
  - PacketAnalyzers
  summary: Create a packet analyzer
  description: Create a new packet analyzer.
  operationId: CreatePacketAnalyzer
  parameters:
  - in: body
    name: analyzer
    description: New packet analyzer
    required: true
    schema:
      $ref: '#/definitions/PacketAnalyzer'
  responses:
    "201":
      description: Created
      headers:
        Location:
          type: string
          description: URI of created analyzer
      schema:
        $ref: '#/definitions/PacketAnalyzer'

When using the go-swagger generated API this results in the API reporting it received an unsupported/unexpected response when an error occurs.
