docker-compose example for single domain deployment

## Is your feature request related to a problem? Please describe.
I get only one domain from my organization (e.g: mydomain.org) , the https reverse proxy has been setup by my organization. I already have some other web apps deployed under this domain's subpath, (e,g : mydomain.org/mettermost)
I would like to know is it possible to setup ocis to only use one single domain, and use different subpath for each components, for exmaple, mydomain.org/ocis, mydomain.org/onlyoffice, mydomain.org/idp, etc.

## Describe the solution you'd like
It would be great to have a docker-compose example that:
* NO internal proxy，as the proxy will be setup by external nginx
* Assign different subpath for different components, so that I can write reverse proxy rule in nginx to forward traffic to different backend components via different path.

Start by reviewing the repository's existing Docker Compose examples and the component routing configuration. Define a deployment example without an internal proxy, with separate subpaths for the components and external nginx forwarding rules. Done means the example can serve the requested components under one domain's subpaths.
