Subject: Move origin-gce roles and playbooks into openshift-ansible

This moves all core functionality into the openshift-ansible repo, adds
the necessary equivalent entrypoint to the openshift-ansible installer
image, and ensures the dynamic inventory mechanisms in openshift-ansible
continue to work.

Notable changes from origin-gce:

* playbook extensions changed to .yml
* dynamic inventory subdirectory created to prevent accidental use
* use the custom entrypoint entrypoint-gcp for this image
* move tasks into openshift_gcp role
