Enable pod security policies
The intention with this change is to disable CAP_NET_RAW (which can be a security vulnerability) for created Pods. kubespray provides the podsecuritypolicy_enabled variable for enabling privileged (for kube-system) and restricted (for everyone else) policies. Enabling this requires binding the KUD_ADDONs to the privileged policy and specifying the security context correctly for Pods running in the default namespace. As of this change, the only difference between the privileged and restricted security policies is the dropping of CAP_NET_RAW in the restricted policy. To use the default restricted policy provided with kubespray, additional changes must be made to the Pods that are run in the default namespace (such as runing as a non-root user, not requesting privileged mode, etc.).
