System-Level Configuration for Live Access Thread Pool Setting

NetBrain currently allows the Live Thread Pool setting to be configured only at the individual Tenant or Front Server level, with no option to manage it as a single global setting. In environments with a large number of Tenants and Front Servers, this requires administrators to update the value manually and repeatedly across every instance to prevent SSH credential lockouts during benchmark task execution. This enhancement would introduce a system-level Live Thread Pool setting that administrators can configure once and apply globally across all Tenants and Front Servers. Customers managing large-scale deployments would benefit from reduced administrative overhead and a lower risk of SSH credential lockouts caused by inconsistent thread pool values across the environment.
