[Revolyssup]

Current behaviour

➜  k8sdebug git:(main) ./k8sdebug logs show -n echo --type deployment
Error: accepts 1 arg(s), received 0
Usage:
  k8sdebug logs show [flags]

Flags:
  -h, --help         help for show
      --only-names   display only names

Global Flags:
  -e, --end-of-file        reverse the order of the logs
      --latest             reverse the order of the log files
      --max-lines int      maximum number of lines to read from the log file (default 10)
      --max-pods int       chronological index of the pod (default 10)

      --tail int           No. of lines to use for diff (default 10)

The above command should give a list of all available deployments in echo namespace so that user can select directly from menu
