Support for config retrieval via 'show running-config view full' for lower-privilege accounts

NetBrain's discovery and benchmark drivers currently rely on the 'show running-config' command, which requires privilege level 15 access on Cisco devices. Some customers manage devices under restricted local accounts with lower privilege levels, where this command cannot be permitted, even though the more limited 'show running-config view full' command is available to them. This enhancement would introduce a driver option to retrieve device configuration using 'show running-config view full' as an alternative to the standard command, configurable in a way that does not affect other tenants or customers in shared, multi-tenant environments. This would allow customers who do not have full administrative access to devices, such as during a transition between service providers, to complete discovery and benchmarking using a reduced set of permitted commands.
