[Starlingx-discuss] heads-up, planning to replace k8s 1.21.3 with 1.21.8

[Chris Friesen]

Hi everyone,

I have a series of reviews up replacing Kubernetes 1.21.3 with 1.21.8 in 
the master branch.  It was discovered that 1.21.3 suffers from higher 
overhead relative to 1.18 (specifically in kube-apiserver and kubelet), 
and the issue seems to be resolved in 1.21.8.

This also means bringing in a slightly newer version of golang, and if 
you have a private Docker registry you may need to download the new K8s 
images.

The main review for Kubernetes itself is 
https://review.opendev.org/c/starlingx/integ/+/824803 if anyone wants to 
track it.
