Updates container image versions for external-dns and kubeip deployme…

…nts (#851)

* Updates repo and version for external-dns deployment

* Updates version for kubeip deployment

* Sets strategy to Recreate for kubeip deployment

When you only have a single replica in a deployment, a rolling update
doesn't always make the most sense, especially if the service isn't user
facing. This change sets the update strategy for the kubeip deployment
to a simple "Recreate", which will just delete the old pod and create a
new one.

* Moves kubeip deployment to kube-system namespace

* Moves kubeip SA to kube-system namespace
