Configurable Concurrency Limit for Discovery and Benchmark Tasks

NetBrain currently does not provide a way to configure or limit the number of concurrent connections used during Discovery and Benchmark tasks. Network segments with a restricted number of available authentication sessions, such as environments with limited TACACS license capacity, can be affected when NetBrain opens more simultaneous connections than the environment can support. This enhancement would allow administrators to set a configurable concurrency value within Discovery and Benchmark task settings to control the maximum number of simultaneous connections. This would help customers with session-constrained network segments avoid authentication failures and maintain stable task execution.
