Description of problem:
Enable the multiplier for the haproxy cartridge, enable the ha for the application. Try to create scalable app and scale up the app to generate the multiple haproxy.
Will meet node execution failure.

Version-Release number of selected component (if applicable):
fork_ami_deploy_873

How reproducible:
always

Steps to Reproduce:
1.Launch fork_ami_deploy_873
2.Enable multiplier for haproxy cartridge
    Scaling:
      Min: 1
      Max: 2
      Multiplier: 2
 Restart ruby193-mcollective service
3.Enable application ha on the broker
#cat /etc/openshift/broker-dev.conf
ALLOW_HA_APPLICATIONS="true"
4.Allow ha for user
#oo-admin-ctl-user -l bmeng --allowha true
5.Restart broker and clear broker cache
6.Create scalable app and scale it up to generate multiple ha


Actual results:
Will meet node execution failure when scale up to the gear which should contain haproxy cartridge.

Expected results:
App with multiple haproxy should be created successfully.
