Fixing podman flags order sequence in create task (#36)

These changes moves the podman flags:
`--storage-opt`, `--storage-driver` and `--cgroup-manager` to be called
before the `run` command.
This fix a execution fail when using some of those flags in the
`molecule.yml` file.

e.g:

this:
```bash
podman --cgroup-manager=cgroupfs
--storage-opt=overlay.mount_program=/usr/bin/fuse-overlayfs
--storage-driver=overlay run -d --name node.local
--privileged=True --volume /dev/fuse:/dev/fuse:rw --tmpfs=/run
--tmpfs=/tmp --hostname=node.local
docker.io/pycontribs/centos:8 /sbin/init
```

instead of this:
```bash
podman run -d --name node.local  --privileged=True
--volume /dev/fuse:/dev/fuse:rw --tmpfs=/run --tmpfs=/tmp
--hostname=node.local --cgroup-manager=cgroupfs
--storage-opt=overlay.mount_program=/usr/bin/fuse-overlayfs
--storage-driver=overlay
docker.io/pycontribs/centos:8 /sbin/init
```
