Choose Edge-optimized or Regional Endpoint Configuration for Custom Domain Names

## Prerequisites

* [x] I am running the latest version. (`up upgrade`)

* [x] I inspected the verbose debug output with the `-v, --verbose` flag.

## Description

I would like the ability to control the type of Custom Domain Name, whether edge-optimised or regional.

## Steps to Reproduce
Add to up.json
```
...
"production": {
"domain": "some-domain.example.com",
...
```
This has created a new Custom Domain name called "some-domain.example.com" AWS Console -> API Gateway -> Custom Domain Names. However this is edge-optimised. As this creates a Cloudfront distribution it incurs a cost. For this reason I would like to create a Regional Endpoint configuration, but I am not sure how to tell up to create one.

I wonder if this related to the underlying issue behind https://github.com/apex/up/issues/681.
