> Currently, SCM first fires the pipeline close command to DN and then, without waiting for ACK, removes the pipeline from its state map. 
> Sometimes, we observed that the pipeline got removed from the DN but didn't get removed from SCM, so it caused the SCM to get stuck in safemode as SCM is expecting the pipelines from DN. So, first, we should remove the pipeline from the SCM pipeline statemap and then fire the close pipeline command to DN.
