A static website hosting service for use in CD.

It aim at providing a service similar to github or gitlab pages for self-hosted
software forges and CI/CD services.

# TODO

## [x] Phase I
- [x] upload /subdomain/<subdomain>/upload -> untar
- [x] serve for any subdomain

## [ ] Phase II

- [ ] store subdomains linked to each upload (which database ? sled ?)
- [x] serve for specific subdomain

## [ ] Phase III

- [ ] config (ex: single page app, custom 404, et c)
    - config in static file, or in api ? (or both ?)
- [ ] simple login (and prepare fail2ban)

Yeah ! A minimal working service !

## [ ] Phase IV

Highly hypothetical

- [ ] upload from web interface
- [ ] ability to set login backend and api OIDC auth
- [ ] subdomain reservation mechanism (usecase: forge reserve subdomains for
      users/orgs)
