b533a8ee3f
This patch adds neutron lBaaS nsxv3 support. The refactor has been done in neutron-lbaas to share the same driver for nsxv and nsxv3. (I7308035d38f2ab15a85096ec30388ef5c3f56ca3). Also load balancer API wrapper for nsxv3 also has been added to vmware-nsxlib in (I0fc80e20551e0994888d8c222a9a620dcb2f6e32). This patch implements the functionality of the following lbaas resources: - loadbalancer - listener - pool - member - healthmonitor If nsx platform doesn't support LB, we will return a dummy driver class. It will raise NotImplementedError if user tries to use LBaaS driver. Note that layer7 support is not in this patch. It will be supported in another path.
