Fixes bug 1043147 Currently, the cisco nexus sub-plugin doesn’t handle the network admin state parameter when it’s updated. The fix would enable the sub-plugin to handle an update of the admin state of the network. In update_network of the nexus sub-plugin, vlan corresponding to that network is added/removed from the nexus interfaces based on the network state. Unit tests are added as well.
