OOD Persistent SSH

Application and ssh wrapper for enabling persistent ssh shells on compute nodes using tmux.

The app requires ood-util and ood-initializers to work.

About

The app creates a file /tmp/$USER/$SLURM_JOB_ID/persist_ssh on the node that it launches on and just provides the user a link to the OOD shell app (/pun/sys/shell/ssh/<node>). When the user tries to SSH to the node through OOD the OOD_SSH_WRAPPER script (ssh_wrapper.sh) checks if a file /tmp/$USER/$SLURM_JOB_ID/persist_ssh exists on the target. If it exists a tmux session is resumed, otherwise a new session is started.
