重置密码API

#流程

##第一步，获取验证码

###Request POST /v2/users/send_security_code

{"username":"somename"}

###Response

{"code":20000,"message":"OK","status":"true"}  
{"code":40401,"message":"No such user","status":"false"}  
{"code":49901,"message":"Too frequent request, try later","status":"false"}  

###注意 接口频率相同username超时30秒，30秒以内第二次调用以上会触发49901

##第二步，凭验证码重设密码

###Request POST /v2/users/reset_password {"username":"somename","security_code":"123456","password":"newpassword"}

###Response

{"code":20000,"message":"OK","status":"true"}
{"code":49901,"message":"Too frequent request, try later","status":"false"}
{"code":40404,"message":"Security code has expired","status":"false"}
{"code":40603,"message":"Security code dismatched","status":"false"}
{"code":40600,"message":"The request you send is invalid.","status":"false"}

###注意 接口频率相同username每600秒调用5次，5次以上49901
