Bug Description
K8s 1.21.3 is giving worse overhead than older versions of K8s (such as 1.18.1 as was used in StarlingX 5). In particular, the steady-state overhead of kubelet and kube-apiserver is higher when there are no pods on the system as well as when there are numerous pods on a node.
K8s 1.21.8 has been tested and gives much better behaviour, especially when there are many pods on a given node. As such we want to move to 1.21.8 instead of 1.21.3.
The main side effect of this is that we also need to bump to a slightly newer version of golang but it's only a patch version bump so nothing should be impacted.
