Update reqparse.py so that pattern is properly set on list objects wh…

…en using option "append"

Using the reqparse option "append" in combination with a "pattern" leads to the wrong validation schema. Example, using the following code:

obj.add_argument('tag', location='args', type=inputs.regex('^[-_a-zA-Z0-9]+$') , action='append', default='', help='Filters obj tagged with the provided tags')

Currently result with the following schema:

{
  name: "tag",
  in: "query",
  type: "array",
  description: "Filters domains tagged with the provided tags",
  pattern: "^[-_a-zA-Z0-9]+$"
  default: "",
  items:
  {
    type: "string",
  },
  collectionFormat: "multi"
}

Which should be:

{
  name: "tag",
  in: "query",
  type: "array",
  description: "Filters domains tagged with the provided tags",
  default: "",
  items:
  {
    type: "string",
    pattern: "^[-_a-zA-Z0-9]+$"
  },
  collectionFormat: "multi"
}

Kind regards
