Improving config overrides

[heatherwoz]

Changes here:

• create more parity between D7 and D8 process - use similar language and offer similar options
• for D8, do not import config after checking for overrides and exiting - use explicit --no flag to prevent this
• for D8, import config after running DB updates rather than before - there is some debate, but this seems to be the recommended practice; it was necessary for the 8.8 -> 8.9/9 upgrades

Awesome! I'm now going to get in the habit of creating pull requests for you to review rather than just committing directly to the main branch.

Weird. That feels backwards to me. I can think of some scenarios where that won't work. But I'm having trouble thinking of scenarios why this change would be needed.

Regardless, I think 95% of the time it shouldn't matter which order, so I'm willing to give it a shot and see how this plays out in the real world.
