Description of problem:
It's failed to show warning messages when git touchpoints reach 90%+ for scaled-up gear, the messages only can be shown for head gear.

Version-Release number of selected component (if applicable):
devenv_4195

How reproducible:
always

Steps to Reproduce:
1. Create a scaled app
rhc app create cpy27s  python-2.7 -s

2. Scale up this app
rhc cartridge scale python-2.7 -a cpy27s --min 2

3. Write some data to head gear and scaled-up gear to make disk quota and inodes reach 90%+
ssh <head_gear_SSH_URL>
ssh <scaled-up_gear_SSH_URL>
After ssh into the gears, do as below:
cd ~/app-root/data
dd if=/dev/zero of=950M.txt bs=1M count=950; ### if quota limitation is 1024MB
for i in `seq 1 75000`; do touch ccy$i.t; done   ### if inodes limitation is 80000

4. Make some changes in local repo
cd cpy27s;
git add . && git commit -amp && git push

Actual results:
