By default `run.sh` invokes `docker run` with the
[`--rm`](https://docs.docker.com/engine/reference/run/#clean-up---rm) option,
making the embark container ephemeral, i.e. it will not persist on the docker
host's file system after the container exits. To override this behavior:
``` shell
EMBARK_DOCKER_RUN_RM=false
run_embark [docker-run-opts] -- [command]
```
Note that if you have `EMBARK_DOCKER_RUN_OPTS_REPLACE=true`, then `--rm` would
need to be provided in `[docker-run-opts]`, i.e. `EMBARK_DOCKER_RUN_RM` will be
effectively ignored.
