If the NVP cluster is in 'readonly-mode' during a maintenance window, some NVP operations may raise a Forbidden error. This is not currently handled correctly, and Neutron server ends up returning 500. This patch addresses the problem by ensuring the right error code is returned. Fixes bug 1204715 Change-Id: Ibd2cac8286a0978a95f9006142c2a405053dfa00
