Move subdomains to query paths.

In more detail:

- Use Django URL namespaces (e.g. `api:bot:infractions`) instead of
  `django_hosts` host argument.
- Update the hosts file setup documentation to remove subdomain entries.
- Update the hosts file setup documentation to mention that the entry of
  `pythondiscord.local` is not required and mainly for convenience.
- Rename the `APISubdomainTestCase` to the more fitting
  `AuthenticatedAPITestCase`, as authentication is all that is left that the
  class is doing.
- Drop dependency to `django_hosts`.
