Restructure the project so the repo and sync are run together

Changes:
- There is one unified docker-compose.yml for both repo and sync
- Both containers are started together, but the maven container spins
until the repo is ready
- The repo is terminated when maven terminates
- The repo is set up at port 80 in the container, 9001 on the host
- The maven container is separated from the host network, only has
connections to the repo

 # Maven Sync Setup
 
-## Repository
-
 _Reposilite_-based Maven Repository Manager acting as a caching proxy.
 
 ```sh
-mkdir data
-cd repo
-./deploy.sh
+./run.sh
 ```
-TODO: something is not working correctly when loading the initial configuration.
-Take the content of the `reposilite.cdn` and paste it into the Configuration window
-after logging in as `admin:secret` on http://localhost:9001 and press _Update configuration and reload_.
-
-## Sync job
-
-Script that can be triggered manually or scheduled.
-
-cd sync
-./sync.sh
 
-Mirror tarballs.
+This starts the reposilite server, then starts maven and makes download all packages defined in the pom's in the `examples/` folder, including their dependencies. These packages are then cached by reposilite in `data/`. The relevant folders are turned into tarballs and saved in the root directory.
