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

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