Remove APEL Server from docker build
Remove APEL Server from docker build

- Moves closer to the docker ideal of 1 service per container
- A seperate REST interface container will also allow scalling
  in order to cope with high demand, where as the Server (specifically the loader)
  does not scale. Previously the two being together prevented any scaling
- /etc/apel is needed for database configuration allowing the REST interface
  to talk to the APEL database
- This directory was previously created by the APEL RPM
