Expose Flavors in LocalQueue Status

[KPostOffice]

What would you like to be added:
Add a status field to LocalQueue which lists out available flavors

Why is this needed:
I would like to be able to see the resource flavors available in each LocalQueue that I have access to

Completion requirements:

This enhancement requires the following artifacts:

• Design doc
• API change
• Docs update

The artifacts should be linked in subsequent comments.

Updating the flavors in status will eat QPS to update the information which is just one step away so I would prefer to understand what is the use-case.

Would it work for you composing these queries:

CQ_NAME=$(kubectl get lq/user-queue -ojson | jq -r .spec.clusterQueue)
kubectl get cq/$CQ_NAME -ojson | jq .spec.resourceGroups\[\].flavors\[\].name

If this works, maybe just need a docs update for "common tasks", or extend kueuectl?

We already have API calls to populate the usage, so this wouldn't add additional calls.

This might not work, depending on the RBAC rules, as users might not have read access to ClusterQueues.

I see, sounds good

The RBAC permission deeply depends on the organization's policies. So, it might be better to add troubleshooting guide or any dedicated task document how to obtain the tied resourceFlavors.

This is exactly the issue we are facing. Letting the users know the flavors is useful since it can give an idea of the capabilities provided by a LocalQueue. (i.e. one flavor may have newer GPUs)
