- Add app_ports table for storing port mappings per app
- Add Port model with CRUD operations
- Add handlers for adding/deleting port mappings
- Add ports section to app detail template
- Update Docker client to configure port bindings when creating containers
- Support both TCP and UDP protocols
Use DataDir/builds instead of /tmp for clone directories so that bind
mounts work correctly when upaas itself runs in a Docker container.
The /tmp directory inside the upaas container isn't accessible to the
Docker daemon on the host, causing bind mount failures.
Also fix test setups to pass Config to deploy service and add delay
to webhook test to avoid temp directory cleanup race with async
deployment goroutine.
