Fix cod_rabbitmq_agents_cloud role throwing error

While I trying to deploy a new CoD to test PR #42 (closed) and PR #65, found the issue with a task in role cod_rabbitmq_agents_cloud.

It's a task with an ansible command module.

TASK [cod_rabbitmq_agents_cloud : Create nossh group] ****************************************************************************************************************************************************************************************
fatal: [ohpc]: FAILED! => {"changed": false, "cmd": "module load cmsh '&&' cmsh -c 'group; add nossh; commit'", "msg": "[Errno 2] No such file or directory", "rc": 2}
