Doc Text:	Previously, the NetApp driver operating in driver_handles_share_servers=True mode could not delete share servers that were created on non-segmented networks. This resulted in clean-up issues that prevented users from creating new shares. With this update, the NetApp driver does not assume that share servers are provisioned only on segmented (VLAN) networks. As a result of this, share servers on non-segmented networks can be cleaned up successfully, and users can create new shares.	Story Points:	---
