Add Factor Testcase System_Bandwidth
JIRA: BOTTLENECK-94 Add factor test to find the bottleneck of system bandwidth. A separate logic is provided to determine what is throughput for a deployed system. Changes: 1. Add testcase script 2. Delete whitespaces 3. Logic fix Change-Id: I37ab9d40d90c585191619d4753eca285fee64dd4 Signed-off-by: yuyang <Gabriel.yuyang@huawei.com>
