shown d5633ebad7 fix(contrib/registry): etcd doKeepAlive does not exit even when client context done (#4669)
Fixed #4668 

```
// client
package main

import (
	"github.com/gogf/gf/v2/frame/g"
	"github.com/gogf/gf/v2/net/gsvc"
	"github.com/gogf/gf/v2/os/gctx"

	"github.com/gogf/gf/contrib/registry/etcd/v2"
)

func main() {
	gsvc.SetRegistry(etcd.New(`etcd.etcd.orb.local:2379`))

	var (
		ctx    = gctx.New()
		client = g.Client()
	)
	client.SetDiscovery(gsvc.GetRegistry())
	res := client.GetContent(ctx, `http://hello.svc/`)
	g.Log().Info(ctx, res)
}

// server
package main

import (
	"github.com/gogf/gf/contrib/registry/etcd/v2"
	"github.com/gogf/gf/v2/frame/g"
	"github.com/gogf/gf/v2/net/ghttp"
	"github.com/gogf/gf/v2/net/gsvc"
)

func main() {
	gsvc.SetRegistry(etcd.New(`etcd.etcd.orb.local:2379`))

	s := g.Server(`hello.svc`)
	s.BindHandler("/", func(r *ghttp.Request) {
		g.Log().Info(r.Context(), `request received`)
		r.Response.Write(`Hello world`)
	})
	s.Run()
}
