**Alternate Terminal Support for Linux**
The `run` script with `cos_117.cfg` spawns xterms for consoles, but users may prefer other terminals such as konsole, gnome-terminal or even cool-retro-term.
To resolve, this commit adds alternate terminal support via:
+ gen_term_run_cfg - Generates run script and config combo for any alternate terminal.
Benefits:
- Consoles will launch in the user's desired terminal when the generated script is executed.
Usage:
```
gen_term_run_cfg <terminal-name>
```
Full Usage:
```
Generate run script and configuration for cray_sim
to launch consoles in alternate terminals instead of
xterm.
Usage: ./gen_term_run_cfg <terminal-name>
Example - ./gen_term_run_cfg cool-retro-term
```
Tests:
- The script was checked in shellcheck with no issues detected.
- Tested on Ubuntu 22.04.3 LTS (aarch64)
- Tested on Arch Linux (x86_64)
