Driver option to retrieve full configuration via 'show running-config all' for Cisco IOS, Router, and SD-WAN devices

NetBrain's discovery and benchmark drivers for Cisco IOS Switch, Cisco Router, and Cisco SD-WAN Router devices currently issue the standard 'show running-config' command, which does not return default or implicit configuration parameters that some configuration assessment workflows require. This enhancement would introduce a driver option to retrieve configuration using 'show running-config all' instead, configurable so that it persists reliably across patches and upgrades and does not affect other tenants or customers in shared environments. Customers who rely on configuration assessment rule sets that depend on complete configuration detail, including default values, would benefit from consistent and accurate results without needing manual driver modifications after each upgrade.
