Use the commands below to provide key information from your environment:
You do NOT have to include this information if this is a FEATURE REQUEST

What version of frp are you using (./frpc -v or ./frps -v)?
0.21.0

What operating system and processor architecture are you using (go env)?
win64

Configures you used:
[common]
server_addr = x.x.x.x
server_port = 9090
token = ssssss
use_encryption = true
use_compression = true
pool_count = 5
http_proxy = http://user:pass@proxyhost:8080

[tcp]
type = tcp
local_ip = 127.0.0.1
local_port = 9999
remote_port = 8888

Steps to reproduce the issue:

frpc -c frpc.ini

Describe the results you received:
返回
C:\frp_0.21.0_windows_amd64>frpc -c frpc.ini
2018/10/28 02:14:33 [I] [proxy_manager.go:300] proxy removed: []
2018/10/28 02:14:33 [I] [proxy_manager.go:310] proxy added: [tcp]
2018/10/28 02:14:33 [I] [proxy_manager.go:333] visitor removed: []
2018/10/28 02:14:33 [I] [proxy_manager.go:342] visitor added: []
2018/10/28 02:14:33 [W] [control.go:113] login to server failed: DialTcpByHttpProxy error, StatusCode [407]
DialTcpByHttpProxy error, StatusCode [407]

Describe the results you expected:
407应该是代理认证失败，相同的代理用户密码用curl就可以connect到frps

Additional information you deem important (e.g. issue happens only occasionally):
看了一下golib/net/proxy.go代码，这一段里好像 auth.Enable 始终没有被赋值

func DialTcpByHttpProxy(proxyHost string, dstAddr string, auth *ProxyAuth) (c net.Conn, err error) {
	if c, err = net.Dial("tcp", proxyHost); err != nil {
		return
	}

	req, err := http.NewRequest("CONNECT", "http://"+dstAddr, nil)
	if err != nil {
		return
	}
	if auth.Enable {
		req.Header.Set("Proxy-Authorization", "Basic "+base64.StdEncoding.EncodeToString([]byte(auth.Username+":"+auth.Passwd)))
	}
	req.Header.Set("User-Agent", "Mozilla/5.0")
	req.Write(c)

Can you point out what caused this issue (optional)
