nicira plugin - perform rollback when router ops fail

Bug Description

The Nicira NVP Quantum plugin sometimes operates 'transactions' on the NVP platform, meaning that several NVP API read/write operations are performed for a given Quantum API operation.

As the Quantum API operation satisfies ACID properties, the same should happen for the operation on the NVP side.

This happens, for instance, when router interfaces are added or removed to a router. In case of NVP failures, the DB operation would complete successfully but the NVP resources might be only partially created.

In case of NVP failures all NVP resources created/modified up to the failure should be rolled back, and the DB operation should be undone.
