RPS will become to 0 in distributed mode

[wcycxp]

Description of issue / feature request

In my code，i set the stop_timeout =10。When I run it in distributed mode, the vitrual user will become to 0 after 10 seconds. But the rps also become to 0.

Environment settings (for bug reports)

• OS:
• Python version: 3.7.1
• Locust version: 0.9.0

code is below:

from locust import HttpLocust,TaskSet,task,runners,main,stats,events
import time,os,json
class UserBehavior(TaskSet):
    @task(1)
    def job11(self):
        start_time = time.time()
        head = {'token':'165c8b3a345540669765ce7c913a7558'}
        with self.client.get("/mock/14962/account/userLogin",catch_response=True) as response:
            #response_time = int((time.time() - start_time) * 1000)
            #if response_time>3000:
             #   response.failure(response_time)
            if response.status_code==200:
                try:
                    res=response.json()
                    result=res['result']
                    if result==False or 'data' not in res.keys():
                        response.failure(res)
                except:
                    response.failure("no data")

class WebUser(HttpLocust):
    task_set = UserBehavior
    start_time = time.time()
    host = "http://yapi.demo.qunar.com"
    min_wait = 0
    max_wait = 0
    stop_timeout = 10

I think the slave doesn't stop reporting empty stats to the master while it's stopped.

Maybe this is solved by #1025 ?
