## What type of PR?

Feature

## What does this PR do?

Apply `DEFAULT_QUOTA` settings to user creation admin ui page.

## Prerequisites
Before we can consider review and merge, please make sure the following list is done and checked.
If an entry in not applicable, you can check it or remove it from the list.

- [ ] ~In case of feature or enhancement: documentation updated accordingly~
- [ ] ~Unless it's docs or a minor change: add [changelog](https://mailu.io/master/contributors/workflow.html#changelog) entry file.~

I'm sorry for that I'm not good at English to update the documentation. But this is not a completed new feature. `DEFAULT_QUOTA` is an existing configuration. I just completed the behaviors. Although this configuration was never documented.
