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

+-	Verify NetworkManager is configured to use dnsmasq:
+
+```sh
+$ sudo vi /etc/NetworkManager/NetworkManager.conf

+Test The Setup
 --------------
 
+1.	cd openshift-ansible/
+2.	Try to list all instances (Passing an empty string as the cluster_id argument will result in all libvirt instances being listed)
