cli to list all possible node-field values for a workflow

[tooptoop4]

https://argoproj.github.io/argo-workflows/cli/argo_retry/ accepts --node-field-selector but I'm struggling to find key/values to pass into it.

I tried different keys (ie field names) from https://argoproj.github.io/argo-workflows/node-field-selector/ and then different formats of values including dag.steps.thestep(0) among 10s of other combos but no luck!

would be great if there was a cli command that accepts argument of workflowname and nodefield, then it returns output of all possible values for that nodefield in that workflow

implementation idea
i imagine this will loop through all nodes of a workflow

argo-workflows/cmd/argo/commands/common/get.go

Line 142 in e09d2f1

} else if _, ok := wf.Status.Nodes[wf.ObjectMeta.Name]; !ok {

then for each node print out all the key/value pairs:

argo-workflows/workflow/util/util.go

Lines 455 to 461 in e09d2f1

	nodeFields := fields.Set{
	"displayName": node.DisplayName,
	"templateName": GetTemplateFromNode(node),
	"phase": string(node.Phase),
	"name": node.Name,
	"id": node.ID,
	}

i'm guessing above won't be available when already archived
i think dag is the trickiest to understand full path at the moment

Could you paste what you tried exactly, including the field name and value?
