Add Calico v2.5 support for Kubernetes v1.8+

Added support for Canal (Calico) v2.5.1, which is required to work with Kubernetes v1.8.0+.

Older versions of Calico relied on ThirdPartyResources API to store it's config data, however this is now fully deprecated in Kubernetes v1.8 and has moved over to CustomResourceDefinitions (CRD). Calico v2.5+ has been updated to use CRD, however there is a manual upgrade process involved to migrate the configuration data across: https://github.com/projectcalico/calico/blob/master/upgrade/v2.5/README.md
