Updates for compatibility with Drupal WxT.

Attempts to get Drupal WxT working with OpenShift.

Relies on two custom cartridges forked from Phase 2

https://github.com/phase2/openshift-php-fpm -> https://github.com/sylus/openshift-php-fpm (modified php.ini.erb to 256M)
https://github.com/phase2/openshift-community-drush-master -> https://github.com/sylus/openshift-community-drush-master

Then customized the build + deploy script based on work done in OpenShift + Phase 2.

Unfortunately there are still a few problems with timeouts but the script does work if you let it run in background and let the background process for drush si to run for 10-15 minutes on a small gear.

Just follow the Readme.md and you should have a working setup in 15 mins.

We should look into how to make this faster and not resorting to having the drush site-install as a background process because technically you will never know when it is done. Unfortunately hit timeouts with OpenShift otherwise.
