Description of problem:

If a gear is idle, request on WebSocket port don't wake it up.


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

OpenShift Online devenv, based on ami-de96d1b7 - devenv_3628

How reproducible:

Always.

Steps to Reproduce:
1. Create a devenv OpenShift Online instance
2. Create a new app using Aerogear cartridge

   rhc create-app pushserver https://raw.github.com/fjuma/origin-server/downloadable/cartridges/openshift-origin-cartridge-aerogear-push/metadata/manifest.yml mysql-5.1  

3. Put cartridge idle

   /usr/sbin/oo-admin-ctl-gears idlegear uuid   

4. Ensure cartridge is idle
 
   /usr/sbin/oo-idler-stats


5. Fire request to SimplePush (netty on :8000 -> :8676 port), for instance to an endpoint or directly to /simplepush

curl -i --header "Content-Type:application/x-www-form-urlencoded" -X PUT -d "version=2" http://pushserver-aerogear.dev.rhcloud.com:8000/endpoint/470dddc2-ce0b-4306-8be3-eaf995218


Actual results:

HTTP 503, cartridge is still idle, you can repeat as many times as you want

Expected results:

HTTP 302, the same for :80 HTTP requests or directly HTTP 200

Additional info:

If I wake up gear with request to :80, it gives me back HTTP 302, subsequent requests return HTTP 200.
