[dpdk-ci] script to determine target repo (was DPDK Lab)

[Xu, Qian Q]

Thanks Thomas and Bruce for your comments. Currently we are trying to start the per patch set performance test investigation and need to know the 
Target repo for each patch set.  
The goal is to get 100% correct repo to go for each patch set. It's important for the credit of the performance result. 
@Thomas, could you provide any script to support the auto-filter after the 17.05 release? Currently, we don't have the ability to make it.
