Configurable CLI Timeout for Long-Running Commands

NetBrain currently enforces a fixed CLI timeout of 5 minutes in Device Settings, which causes long-running commands, such as 'show tech-support' on certain platforms, to fail before completion. This enhancement would allow administrators to configure or extend the CLI timeout value for command execution beyond the current default, independent of other module-specific timeout controls. Customers running commands that require extended execution windows would benefit from reduced task failures and more reliable diagnostic data collection.
