Allow KuD installer to specify Kubespray 2.14.1 or 2.16.00.9.2

The default is 2.14.1 (the existing value).  Setting
KUBESPRAY_VERSION=2.16.0 in the installer environment uses the newer
Kubespray version.

The newer Kubespray version installs Kubernetes 1.20.7.  Kubernetes
1.20.7 comes with following caveats:
- The Virtlet addon is disabled; it does not work with 1.20.7.  This
  requires removing the plugin_fw test as well.
- Kubernetes 1.20.7 removed support for basic auth.
