Bug Description

Description:

#1839384 was closed, but left a potential issue.

If a volume is attached to 2 instances, and they both terminate the connection at the same time, the driver will leave the connections untouched.

Steps to reproduce:
1. Attach an iSCSI volume to 2 instances
2. Remove the volume from the instances at the same time (might be very difficult)

Expected behavior:
Have the LUNs unmapped.

Actual behavior:
LUNs remain mapped.

We might need to add a coordination lock to VolumeManager.terminate_connection.
