#### What this PR does / why we need it:
Force to add environment variables `HALO_WORK_DIR` and `SPRING_CONFIG_LOCATION` into Dockerfile. After that, we can configure `application.yaml` in working directory as we want.
Please note that we can not configure Halo working directory in `/root/.halo2/application.yaml` directly. Use environment variable `HALO_WORK_DIR` instead.
