* Fix: install policy controller on kdd too
* Remove the calico_policy_version condition altogether
* Install policy controller both on canal and calico under same condition

* add calico_datastore variable to policy controller role
* add missing clusterrole rules for calico policy controller
* disable calico kube controller when kdd mode is used for versions < 3.6
* Refactor downloads to use download role directly
Also disable fact delegation so download delegate works acros OSes.

By default Calico CNI does not create any network access policies
or profiles if 'policy' is enabled in CNI config. And without any
policies/profiles network access to/from PODs is blocked.
K8s related policies are created by calico-policy-controller in
such case. So we need to start it as soon as possible, before any
real workloads.
This patch also fixes kube-api port in calico-policy-controller
yaml template.
Closes#1132
