This adds config options to enforce default resource (cpu,mem) limits on
k8s pod labels. With this, we can ensure all pod nodes have resource
information set on them. This allows to account for max-cores and
max-ram quotas for k8s pod nodes. Therefore also adding these config
options. Also tenant-quotas can then be considered for pod nodes.
