REST API Endpoint for Direct CLI Command Execution on Devices

NetBrain's REST API does not currently provide a method to execute CLI commands directly on devices and return the output through an API call. This enhancement would introduce a new API endpoint that allows external systems to send CLI commands to one or more devices and receive the resulting output programmatically. Customers integrating NetBrain with automation, orchestration, or scripting tools would gain the ability to perform ad hoc command execution and data retrieval without relying on the NetBrain user interface, improving efficiency for automated network operations.
