Separate source repo from almalinux-vault

Hello,

Can we have a chance to separate source repository from `almalinux-vault`? For example, `almalinux-source`.

I want to mirror the AlmaLinux source repository but not the entire almalinux-vault.

Currently, following two directories are seen via rsync.

```
rsync --list-only rsync://rsync.repo.almalinux.org/
almalinux almalinux repository
almalinux-vault almalinux vault repository
```

Here are requirements I'm thinking
1. Create `almalinux-source` directory and put source repos there.
2. Souce repo of older versions are supposed to be put in vault
3. Modify mirror service to return regional mirrors if necessary:
for example, [this URL](https://mirrors.almalinux.org/mirrorlist/9/baseos-source) can return
https://mirrors.somewhere.example.jp/almalinux-source/9.2/BaseOS/Source/
additional to repo.almalinux.org.
