Allow to pass the verbosity level to the --verbose long option.

[pfrenssen]

The help text for the verbosity option mentions that it is possible to pass a value to set the verbosity level:

  -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

However, when I try this I get an error message:

$ php application.php demo:greet Fabien --verbose=3

  [Symfony\Component\Console\Exception\RuntimeException]  
  The "--verbose" option does not accept a value.         

The -vvv option works fine, but the POSIX long option --verbose doesn't accept a value. This is clearly the intention since these values are being read in Application::configureIO():

            if ($input->hasParameterOption('-vvv', true) || $input->hasParameterOption('--verbose=3', true) || $input->getParameterOption('--verbose', false, true) === 3) {

The solution is to simply change the input option from VALUE_NONE to VALUE_OPTIONAL.
