[update:execute] Adding the ability to accept all updates via a command argument

[lalop]

Since #4027 we have to explicitly accept updates before they are run.

When using drupal console in non interactive context this isn't possible, so I could be great to add an argument to accept by default all updates.

On most cli application -y is used for that.
Maybe this can become an option used more globally, like the verbosity one ?

I can work on this kind of feature

Awesome @lalop would be great to check if we could include in next week release 1.9.1
