Describe the PR
Support go-playground/validator.
Support for parsing more tags of validator, such as max\min\oneof.

example:

type JsonResponse struct {
	Errno  int         `json:"errno" validate:"required,max=1000,min=10"`
	ErrMsg string      `json:"errmsg" validate:"required,max=1000,min=10,oneof=success fail"`
	Data   interface{} `json:"data"`
}

{
    "response.JsonResponse": {
            "type": "object",
            "required": [
                "errmsg",
                "errno"
            ],
            "properties": {
                "data": {},
                "errmsg": {
                    "type": "string",
                    "maxLength": 1000,
                    "minLength": 10,
                    "enum": [
                        "success",
                        "fail"
                    ] 
                },
                "errno": {
                    "type": "integer",
                    "maximum": 1000,
                    "minimum": 10
