Sort out arm64 build job name format

[kiwik]

Thank you for reporting bug!

Describe the bug

Some arm64 job names don't apply OpenLab job naming notations, maybe cause some confusion, we should keep consistent for these same type jobs.

[nodesets.yaml] The nodesets contains some "arm64" [1], it seems we should also change it. But it will break some online CI, so I think blew thing should to be done:

1. Keep the arm64 and aarch64 at first
2. Change all nodesets(in job defination) to aarch64.
3. Remove all arm64.

Yes, I found this too

Before nodesets.yaml is changed, we also should address nodepool config.

[cloud provider image name]
the vexxhost image should be changed to aarch64

[nodepool.yaml]

• labels.name: change to ubuntu-xenial-aarch64
• vexxhost-openlab.cloud-images.name: change to ubuntu-xenial-aarch64
• vexxhost-openlab.cloud-images.image-name: change to openlab-ubuntu-xenial-aarch64
• vexxhost-openlab.pools.labels.name: ubuntu-xenial-aarch64
• vexxhost-openlab.pools.lables.cloud-image: ubuntu-xenial-aarch64

IMO, we should do nodesets.yaml first, and then do the job defination change, otherwise we will require 2 times name format in job.name and job.nodeset . It will bring some confusing on upstream community like containerd, and envoy.

And the otherthing, I didn't see any official announcement in Linux or ARM, anyone found it? Because the project like containerd and envoy jobs are defined in their own repo, and should pr with a convincing proof. (The only thing I can think is that when we type the uname -m or unname -a, the linux name is the aarch64 rather than arm64)
