Change Kubernetes version in controller config from `1.20.X` to `1.21.9`

# Reboot controller(s) one by one

Wait each time for controller to join and all pods running.

# Replace worker nodes
|
6. Replace worker nodes
|
||||||
|
Eg. by doubling `desired` for each worker ASG,
|
||||||
|

|
||||||
|
finally reset `desired` for each worker ASG which will terminate the old workers.

If pods seem stuck, eg. fluent-bit shows NotReady *after* control nodes have been upgraded
