feat: add command line flags for automation

[gillyb]

addresses #1698

Adds cli arguments to skip questions:

• --all-changed - for automatically selecting all changed packages.
• --minor - for automatically marking them all as minor changes.
• --patch - for automatically marking them all as patches.
• --summary - to add a given summary.

All of these can work separately to skip just some of the questions.

@Andarist @bluwy (tagging some people i saw that are core contributors here and could probably answer) -

Is this something that you are willing to accept ?
If so, I will do changes required to make the code coverage check pass.. Don't want to do extra work if this is something you don't want to add to the project at all.
