exec collector is running in all pods matched the selector

[nvanthao]

Bug Description

Our doc states that

When the selector refers to more than one replica of a pod, the exec collector will execute in only one of the pods

Expected Behavior
Only exec in 1 pod rather than all pods matched the selector

Steps To Reproduce

• Run exec collector to a Deployment with 2 replicas
• Notice exec are running in 2 pods

Additional Context

• Troubleshoot version: 0.93.2

troubleshoot/pkg/collect/exec.go

Lines 86 to 92 in 53113c0

	for _, pod := range pods {
	stdout, stderr, execErrors := getExecOutputs(ctx, clientConfig, client, pod, execCollector)
	path := filepath.Join(execCollector.Name, pod.Namespace, pod.Name)
	if len(stdout) > 0 {
	output.SaveResult(bundlePath, filepath.Join(path, execCollector.CollectorName+"-stdout.txt"), bytes.NewBuffer(stdout))
	}

Is this a bug in the collector, or the docs? I would have expected a deployment with 2 replicas to run 2.
