Description of problem:
Given a scalable application is scaled up to 2 gears, when the haproxy processes running on the head gear(first gear) is terminated(killed), the app can not successfully auto scale down after a certain time if there is no traffic to the app.

Version-Release number of selected component (if applicable):
On devenv_3540

How reproducible:
Always

Steps to Reproduce:
1. Create a scalable application, scale it up to 2 gears
2. ssh into the first gear(head gear) of the app, kill all haproxy processes
3. Do not access the app, wait for some time, then check that the app is auto scaled down

Actual results:
The app won't auto scale down

Expected results:
The app should auto scale down now that multiple load balancers are implemented.

Additional info:
The app will scale down if we don't terminate the haproxy processes on the head gear.
