composer: --no-interaction when discovering available options (#2348)

The composer module always uses the no-interaction option if it
discovers it _after_ calling "composer help ..." but not on the help
call itself. The lack of this option caused composer to not exit when
called through the ansible module.

The same example command when ran interactively does not prompt for user
interaction and exits immediately. It is therefore currently unknown why
the same command hangs when called through the ansible composer module
or even directly with the command module.

Example command which hangs:
php /usr/local/bin/composer help install --format=json
