Bug Description

Example:
Create a k8s cluster (for example using CMX with replicated cluster create --distribution k3s) and deploy netshoot in the default namespace. Make sure the label for app is specified.
Exec into the netshoot container and create the folder /tmp/test and also some subfolders and files.
Execute the following spec using kubectl support-bundle

apiVersion: troubleshoot.sh/v1beta2
kind: SupportBundle
metadata:
  name: sample
spec:
  collectors:
  #Copies htdocs folder
    - copy:
        selector:
          - app=netshoot
        namespace: default
        containerPath: /tmp/test
