Allow to apply v1/List "resources"

[joaquimrocha]

Description

Users may want to apply lists of resources in the form of a v1/List kind but this is not a regular resource in K8s. See kubernetes/kubectl#837 .

Here is an example of such list: https://kubernetes.io/docs/concepts/policy/resource-quotas/#resource-quota-per-priorityclass

Impact

Headlamp doesn't allow this kind of list to be applied as its expecting only regular resources (with a kind and a metadata.name).
Moreover, the resources defined in the list will not get the namespace automatically added since we're checking for a regular resource.

Expected behavior

Headlamp allows to apply List kind objects, and adds the default namespace to any resources in the list that need it.

I can pick this up!

[joaquimrocha]

@siddhant1 , yes, please go ahead. It's probably better to do it after #809 is merged.

[joaquimrocha]

The #809 is merged now. @siddhant1 , do you still want to work on this?

[siddhant1]

Yes, can you pass me the setup instructions @joaquimrocha

[joaquimrocha]
