cloudwatch command11ExternalLoginNodeDeconfigure is incorrect.

[gwolski]

After configuring a cluster, CloudFormation Outputs provides command11ExternalLoginNodeDeconfigure. Here is an entry from one of my stacks:

sudo /opt/slurm/tsi3/config/bin/external_login_nodes_deconfigure.sh && sudo umount /opt/slurm/tsi3

Unfortunately, the first shell script is really:

/opt/slurm/tsi3/config/bin/external_login_node_deconfigure.sh

"node" vs "nodes"...

In addition, the ansible playbook seems to do the umount:

TASK [ParallelClusterExternalLoginNodeDeconfigure : Unmount /opt/slurm/tsi3] *******************************************************************************************************************************************
changed: [local]

TASK [ParallelClusterExternalLoginNodeDeconfigure : Show umount results] ***********************************************************************************************************************************************
ok: [local] => 
  msg: |-
    umount_results: {'changed': True, 'stdout': 'Mount point is hung. Source has already been deleted.\n/opt/slurm/tsi3 is not a mountpoint\n/opt/slurm/tsi3 already unmounted.', 'stderr': "+ timeout 1s /opt/slurm/tsi3\ntimeout: failed to run command ‘/opt/slurm/tsi3’: Permission denied\n+ echo 'Mount point is hung.

yet, the CloudFormation Output command11 has a sudo umount of same mount point so that command fails.
Also not sure how to interpret all the info that comes from ansible w.r.t. the "Show umount results" section?

Might be nice if you document a bit more what this deconfigure does? for some reason it copies the config to /tmp/_config and then deletes it? Why?
