Graduate SeccompDefault feature to beta
As outlined in the KEP, we now graduate the Kubelet feature to beta which means that it is enabled by default. The corresponding Kubelet flag still defaults to `false`, but we now have the chance to e2e test the feature by using a new serial test case. KEP: kubernetes/enhancements#2413 Signed-off-by: Sascha Grunert <sgrunert@redhat.com>
