__Description__

Fix inventory bug in ansible_runner when host list is provided with multiple hosts.

It ought to be handled by ansible_runner lib, workaround by using `--inventory` arg in cmdline.

Support mpi mode in runner:
* concate mpirun command
* support mca and env config
* prepare hostfile and update Ansible host pattern

Support `--host-list` for deploy and run commands.

Before this change, an inventory file is needed to use `sb deploy/run`.
Now, `--host-list localhost` or `-l localhost` is sufficient for quick try.

Implement ansible client and runner:
* add ansible client
* add deploy and check_env playbooks
