[Console] Note about semantic verbosity methods & OutputInterface

[apfelbox]

Hi,

the part about the more semantic methods in The Console Component > Creating a basic Command > Verbosity Levels could include a small note:

The semantic methods (isQuiet, isVerbose, etc.) are only defined in the implementation class, not the interface. So if you typehint against the interface (as you should), your IDE will complain about missing methods.

Maybe a small note there would clear that up? Or is it not necessary? What do you think?

@apfelbox thanks for opening this issue. I agree that this information could be useful ... but I have doubts whether this may be too much.

@javiereguiluz thanks for your response.

I thought the same thing. On one hand, one should not cram all possible information into the docs, on the other hand this can be quite a puzzling experience. I just wanted to send in the hint about this possible issue, not sure on how to proceed here.

I came here thinking the methods did not actually exist and the document was wrong. I did not realize phpstorm was type hinting this way. So it's definitely confusing and I thought I was doing something wrong.

Let's add a little sentence to this section: "For backwards compatibility, these methods do not exist in the interface until Symfony 3.0."
