Download Calico KDD CRDs (kubernetes-sigs#7372)

* Download Calico KDD CRDs

* Replace kustomize with lineinfile and use ansible assemble module

* Replace find+lineinfile by sed in shell module to avoid nested loop

* add condition on sed

* use block for kdd tasks + remove supernumerary kdd manifest apply in start "Start Calico resources"

(cherry picked from commit 1c62af0)
