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

+GCE external inventory script
+=================================
+
+Generates inventory that Ansible can understand by making API requests
+Google Compute Engine via the libcloud library.  Full install/configuration
+instructions for the gce* modules can be found in the comments of
+ansible/test/gce_tests.py.
+
+When run against a specific host, this script returns the following variables
+based on the data obtained from the libcloud Node object:
+ - gce_uuid
+ - gce_id
+ - gce_image
+ - gce_machine_type
+ - gce_private_ip
+ - gce_public_ip
+ - gce_name
+ - gce_description
+ - gce_status
+ - gce_zone
+ - gce_tags
+ - gce_metadata
+ - gce_network
+
+When run in --list mode, instances are grouped by the following categories:
+ - zone:
+   zone group name examples are us-central1-b, europe-west1-a, etc.
+ - instance tags:
+   An entry is created for each tag.  For example, if you have two instances
+   with a common tag called 'foo', they will both be grouped together under
+   the 'tag_foo' name.
+ - network name:
+   the name of the network is appended to 'network_' (e.g. the 'default'
+   network will result in a group named 'network_default')
+ - machine type
+   types follow a pattern like n1-standard-4, g1-small, etc.
+ - running status:
+   group name prefixed with 'status_' (e.g. status_running, status_stopped,..)
+ - image:
+   when using an ephemeral/scratch disk, this will be set to the image name
+   used when creating the instance (e.g. debian-7-wheezy-v20130816).  when
+   your instance was created with a root persistent disk it will be set to
+   'persistent_disk' since there is no current way to determine the image.
+
+Examples:
+  Execute uname on all instances in the us-central1-a zone
+  $ ansible -i gce.py us-central1-a -m shell -a "/bin/uname -a"
+
+  Use the GCE inventory script to print out instance specific information
+  $ contrib/inventory/gce.py --host my_instance
