Global FQDN Trim Setting for CLI-Parsed Hostnames

NetBrain currently applies FQDN trimming only to hostnames retrieved via SNMP, with no equivalent centralized option for hostnames retrieved via CLI. Each device driver implements its own CLI hostname parsing logic independently, requiring per-driver customization to strip domain suffixes. This enhancement would introduce a global setting, similar to the existing SNMP FQDN trim option, that enables or disables FQDN trimming uniformly for CLI-parsed hostnames across all drivers. Customers managing large, multi-vendor environments would benefit from consistent short-hostname formatting without maintaining custom logic for each driver.
