Description (partial)

Symptom:
Observing segmentation fault when performing multiple  stcli drnetwork cleanup simultaneously.  Management layer for DR is observing race condition when multiple  stcli drnetwork cleanup are invoked simultaneously.

Conditions:
When multiple "stcli drnetwork cleanup" simultaneously (if the requests are invoked very closely <3ms ) it may create multiple tasks for cleaning up the DR network.

These task generate simultaneous requests to below layer in stack,  making the state inconsistent thus resulting in a segmentation fault.
