Coreos fixes

On CoreOS where there is no package management, perform zero-trip
loops instead of throwing an exception for iterating over a member
of an undefined variable.

On CoreOS the binaries are not installed in /usr/local/bin.

Add kubernetes.default.svc in certs dns

Implemented Dynamic Provisioning of PersistentVolumes with cinder

Changed path to hosts ssl certs from /usr/share/ca-certificates to /etc/ssl/certs/ which fixes https problems in kube-controller-manager and kube-apiserver (#189) caused by the lack of certificates on debian and redhat based systems.

When kubespray is deployed on OpenStack, the kube-controller-manager is now aware of the cluster and can create new cinder volumes automatically if the PersistentVolumeClaims are annotated accordingly.
Note that this is an alpha feature of kubernetes 1.2

Fixing deprecation warnings regarding bare variables and apt

Implemented cloud-provider integration for OpenStack

Reverted deletion of "changed_when: False" for Task "Install python-dnf for latest RedHat versions". Deleted "changed_when: False" on Task "Install latest version of python-apt for Debian distribs" to get notified when kubespray has installed a new package version.

Currently kubespray does not install kubernetes in a way that allows cinder volumes to be used. This commit provides the necessary cloud configuration file and configures kubelet and kube-apiserver to use it.
