[self:update] Override files while updating the console

[itsdarrylnorris]

Problem / Motivation

It a little bit annoying doing a drupal init --override every single time we self-update our console. Specially with the updates that we do frequently in Drupal Console.

Solution

• We should add a question to run init --override when running drupal self-udpate. This question by default should be enable as "yes".
