not have access to the env directly.
@feluelle @ashb -> the ENV approach is good to go. Seems this has the right
characteristics. - it will take precedence over other methods
(conf/commandline) but you can still specify other options. So I think for CI
image it's good to go - but for production image definitely this approach is
better:
```
export GUNICORN_CMD_ARGS="${GUNICORN_CMD_ARGS:-} --worker-tmp-dir /dev/shm"
```
I also decided to use /dev/shm as suggested by
