ask function: Call to a member function getOutput()

[puxiaokang]

Just for secure, I can't write host password in code. So I try ask function.

when I call ask or askHiddenResponse for ask password, the function throw this error:

Fatal error: Call to a member function getOutput() on a non-object in vendor/deployer/deployer/src/functions.php on line 511

example:

<?php
require 'recipe/symfony.php';
$password = askHiddenResponse("Host password: ");

server('prod', 'HOST', 22)
     ->user('USER')
     ->password($password);

If ask in task callback, It's success. but I can set server.password:

task('auth', function(){
    $password = askHiddenResponse("Host password: ");
    env('server.password', $password);
});
before('deploy', 'auth');

-- throw exception
The parameter `server.password` cannot be set, because `server` is protected.

You can specify password to null:

server('prod', 'HOST', 22)
     ->user('USER')
     ->password(null);

And you will be asked for password.

@ZhukV can you add docs about this functionality?

is ask and friends not supposed to be run at the top level?
(as I ran into the same error as I dont invoke it within a task it seems).

if this is the case it would be great to throw a proper exception which tells the dev that the function/method he is trying to use requires a Context (which means needs to be called within a task())

@staabm this will be cool. Can you create PR with this?
