Dynamically create the service_conf.yaml file by replacing environment variables from .env (infiniflow#3341)

### What problem does this PR solve?

This pull request implements the feature mentioned in infiniflow#3322. 

Instead of manually having to edit the `service_conf.yaml` file when
changes have been made to `.env` and mapping it into the docker
container at runtime, a template file is used and the values replaced by
the environment variables from the `.env` file when the container is
started.
 

### Type of change

- [X] New Feature (non-breaking change which adds functionality)
