Steps to reproduce:

1. Create an openshift-origin instance on AWS
2. Setup the rhc tools
3. Install the ag-push cartridge

Issues:

1. The mysql-5.1 is missing from the default existing origin cartridges

The fact that mysql-5.1 cartridge is missing from the default origin cartridges makes harder the push cartridge's installation on private cloud environments. I had to perform a manual installation of the my-sql-5.1 cartridge and clear the broker's cache. I spent much time to find out that the broker's cache should be cleared in order to see the my-sql-5.1 cartridge in the cartridges list. All the required dependencies for the push cartridge's installation should exist.

2. When executing "rhc app create pushserver https://cartreflect-claytondev.rhcloud.com/reflect?github=aerogear/openshift-origin-cartridge-aerogear-push mysql-5.1", the application is not created and I receive the error:

Creating application 'pushserver' ...
Unable to complete the requested operation due to: Node execution failure (error getting result from node)..
Reference ID: ed4fa1a09eacef34c68b0c0a0bb5a395

3.
I also tried to execute: "rhc create-app pushserver https://raw.github.com/fjuma/origin-server/downloadable/cartridges/openshift-origin-cartridge-aerogear-push/metadata/manifest.yml mysql-5.1"

The application was create and deployed. However the JBoss server startup fails due to missing environment variables.
