Features:  
- Introduce functionality to add multiple security groups for a node ([hpc-factory#203](https://gitlab.rc.uab.edu/rc/hpc-factory/-/issues/203))
- Enabling node_exporter for `ssh-proxy`, `gpfs5-ood`, `http-proxy` node

Open Issue:  
- Data transfer (scp) slow down via ssh proxy ([devops#597](https://gitlab.rc.uab.edu/rc/devops/-/issues/597))
- Need to update project README for developers for [self-reg-form](https://gitlab.rc.uab.edu/rc/self-reg-form) and [xnat](https://gitlab.rc.uab.edu/rc/xnat) repo
- Blocked IP can’t be removed from sshpiper without killing all sessions, pending group routing PR ([tg123/sshpiper#536](https://github.com/tg123/sshpiper/pull/536)) acceptance to rebuild latest release

Notes:  
We will cutover the IP address of `ssh-proxy` and `http-proxy` nodes at 5pm
