allowEmptyValue flag is ignored

[AlekseyMko]

Hello, looks like allowEmptyValue flag is not validated

yuml snippet:

paths:
  /storyInfo:
    get:
      tags:
        - userId
      summary: Detailed information about story
      operationId: storyInfo
      parameters:
        - name: storyId
          in: query
          required: true
          schema:
            type: string
          allowEmptyValue: false

request url:
/api/storyInfo?storyId or /api/storyInfo?storyId=

AR: Validator accepted the query, the handler was called
ER Validator should throw an error

@AlekseyMko thanks for the issue. this certainly needs to be added
Are you interested in taking a crack at? it believe this requires we add custom ajv keyword.
if interested, let's chat on gitter

FYI: OpenAPI spec describes this as not recommended and likely to be removed.

allowEmptyValue | boolean | Sets the ability to pass empty-valued parameters. This is valid only for query parameters and allows sending a parameter with an empty value. Default value is false. If style is used, and if behavior is n/a (cannot be serialized), the value of allowEmptyValue SHALL be ignored. Use of this property is NOT RECOMMENDED, as it is likely to be removed in a later revision.

openapi notes that The default should be false, which is not honored by the validator. will look into it

@AlekseyMko this is fixed in v3.5.0.
