* Add support for arm images for hyperkube, kubeadm and cni_binary

* Add dummy etcd checksum for arm

This commit adds dummy etcd checksum for arm to avoid "no attribute" error
during setup.

* Add etcd host assert check

* Add 1.13.4 checksums of kubeadm and hyperkube for arm

* Update checksums of kubeadm and hyperkube for arm

* Add dummy checksums for calicoctl_binary_checksums dict

* disable gather_facts because it causes tests to fail
