Configuration updates for latest builds and major refactor

Configuration updates for latest builds
- Switch to using create-node-config
- Switch sdn services to use etcd over SSL
- This re-uses the client certificate deployed on each node
- Additional node registration changes
- Do not assume that metadata service is available in openshift_facts module
- Call systemctl daemon-reload after installing openshift-master, openshift-sdn-master, openshift-node, openshift-sdn-node
- Fix bug overriding openshift_hostname and openshift_public_hostname in byo playbooks
- Start moving generated configs to /etc/openshift
- Some custom module cleanup
- Add known issue with ansible-1.9 to README_OSE.md
- Update to genericize the kubernetes_register_node module
  - Default to use kubectl for commands
  - Allow for overriding kubectl_cmd
  - In openshift_register_node role, override kubectl_cmd to openshift_kube
- Set default openshift_registry_url for enterprise when deployment_type is enterprise
- Fix openshift_register_node for client config change
- Ensure that master certs directory is created
- Add roles and filter_plugin symlinks to playbooks/common/openshift-master and node
- Allow non-root user with sudo nopasswd access
- Updates for README_OSE.md
- Update byo inventory for adding additional comments
- Updates for node cert/config sync to work with non-root user using sudo
- Move node config/certs to /etc/openshift/node
- Don't use path for mktemp. addresses: https://github.com/openshift/openshift-ansible/issues/154

Create common playbooks
- create common/openshift-master/config.yml
- create common/openshift-node/config.yml
- update playbooks to use new common playbooks
- update launch playbooks to call update playbooks
- fix openshift_registry and openshift_node_ip usage

Set default deployment type to origin
- openshift_repo updates for enabling origin deployments
  - also separate repo and gpgkey file structure
  - remove kubernetes repo since it isn't currently needed
- full deployment type support for bin/cluster
  - honor OS_DEPLOYMENT_TYPE env variable
  - add --deployment-type option, which will override OS_DEPLOYMENT_TYPE if set
  - if neither OS_DEPLOYMENT_TYPE or --deployment-type is set, defaults to
    origin installs

Additional changes:
- Add separate config action to bin/cluster that runs ansible config but does
  not update packages
- Some more duplication reduction in cluster playbooks.
- Rename task files in playbooks dirs to have tasks in their name for clarity.
- update aws/gce scripts to use a directory for inventory (otherwise when
  there are no hosts returned from dynamic inventory there is an error)

libvirt refactor and update

- add libvirt dynamic inventory
- updates to use dynamic inventory for libvirt

+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
+  $ plugins/inventory/gce.py --host my_instance
