Fix calico CNI support

[djschaap]

Resolves #469

Recent releases of Calico (>=3.15) seem to prefer being installed with the Tigera operator. This commit handles that.

cni_pod_cidr is also injected into the Installation object, as Calico and Tigera seem to ignore the networking.podSubnet set within the kubeadm-config ConfigMap.

These results were generated with Rangefinder, a tool that helps predict the downstream impact of breaking changes to elements used in Puppet modules. You can run this on the command line to get a full report.

Exact matches are those that we can positively identify via namespace and the declaring modules' metadata. Non-namespaced items, such as Puppet 3.x functions, will always be reported as near matches only.
