The ideal should be achieved under ASG, so that when a node is newly created, it will have the corresponding taint.
However, this may require upgrading infra CF. Therefore, the approach here is a supplement; we will perform a check as soon as the workspace node is created and add the corresponding label and taint.

What does not support the NoSchedule taint? |

Adding ✔️ to unblock.
Please see this question: #20652 (comment)
Depending on which workloads are impacted (metrics, logs), we should consider a follow-on PR for prereqs.
All of the things you mentioned are tolerated, only some of the customized optional addons are not. |

Description
[node-labeler] Refactor node labeling to use taints instead of labels
Note: It's not a long-term taint, so we don't need to worry too much about interfering with the scheduling of other daemonsets, and I've checked our daemonsets at GCP and AWS, and the vast majority of them tolerate the NoSchedule taint

How to test
The best testing method is to use a cell or a ephemeral workspace cluster.
I ran loadgen in my testing cell, it works without problem.
