Right now, the message `To search for a specific service, re-run this command with a search term. (e.g. debug:container log)` is displayed to the user whenever the command is being run. (Except when the search term is given).

But if a user runs e.g. `debug:container --parameters`. This message is out of scope since the user is looking for information about parameters, not services.

This PR will update the command to give better output to the user.

`debug:container`
Will keep current behaviour
`debug:container --parameters`
Will hint how to search for specific parameter
`debug:container --tags`
Will hint how to search for specific tag
