[REQ][Golang]Support value validation

Is your feature request related to a problem? Please describe.

for a spec with value validation (maxLength, maximum, required...)

openapi: 3.0.3
info:
  version: 1.0.0
  title: Example
servers:
  - url: http://localhost:8080
paths:
  /data:
    get:
      responses:
        200:
          description: example response
          content:
            application/json:
              schema:
                type: object
                required: [id]
                properties:
                  id:
                    type: string
                    maxLength: 10

generate go client by v5.4.0 generate -i openapi.yml -g go
and write code

package main

import (
	"context"
	"fmt"
	openapi "github.com/GIT_USER_ID/GIT_REPO_ID"
	"net/http"
)

func main() {
	go http.ListenAndServe("127.0.0.1:8080", http.HandlerFunc(func(writer http.ResponseWriter, request *http.Request) {
		writer.Header().Add("Content-Type", "application/json; charset=utf8")
		writer.Write([]byte("{}"))
	}))
	data, _, err := openapi.NewAPIClient(openapi.NewConfiguration()).DefaultApi.DataGet(context.Background()).Execute()
	fmt.Println(data, err)
}

will output

&{} <nil>

neither client side nor server side validate parameter.

Describe the solution you'd like

import some third library to validate data with schema.
or generate validate code with template

Describe alternatives you've considered

Additional context

Start by reproducing the example with the supplied OpenAPI YAML and the generate -i openapi.yml -g go command, then inspect the generated Go client and server behavior shown in the issue. Done means value constraints such as maxLength, maximum, and required are validated on the requested generation targets, with the validation approach defined.
