Guard against creating multiple groups with the same GID?

[willfurnass]

Should FD guard against this?

With FD r2019.2:

directory (advanced)>group create --gid 99999 testgrp1
------------- group create successful -------------
directory (advanced)>group create --gid 99999 testgrp2
------------- group create successful -------------
directory (advanced)>group list
╔══════════════════╦════════════════════════════════╦═══════════╗
║ Group name       ║ Description                    ║ GID       ║
╠══════════════════╬════════════════════════════════╬═══════════╣
║ testgrp1         ║                                ║ 99999     ║
╠══════════════════╬════════════════════════════════╬═══════════╣
║ testgrp2         ║                                ║ 99999     ║
