ocata branch -- lbaasv2 with VMware driver failed to start q-lbaasv2

[alex kang]

I have NSX-v plugin devstack (backend is NSX + VC) with latest master/ocata release.

With enabled lbaas-v2 (without octavia) I got Error of:

   Invalid: Multiple default providers for service LOADBALANCERV2

It seems the default provider octavia is enabled too and causing multi-provider being detected.

###
### the devstack refer to lbaasv2 in
###

session [[post-config|$NEUTRON_CONF]] has:

[DEFAULT]
# api_workers=0

[service_providers]
service_provider = LOADBALANCERV2:VMWareEdge:neutron_lbaas.drivers.vmware.edge_driver_v2.EdgeLoadBalancerDriverV2:default

###
### and in local.rc session has:
###
enable_plugin vmware-nsx https://git.openstack.org/openstack/vmware-nsx $REPO_BRANCH
enable_service vmware_nsx_v

according to neutron-lbaas README file, to enable a different driver need to use NEUTRON_LBAAS_SERFICE_PROVIDERV2.

update local.rc with
NEUTRON_LBAAS_SERVICE_PROVIDERV2=LOADBALANCERV2:VMWareEdge:neutron_lbaas.drivers.vmware.edge_driver_v2.EdgeLoadBalancerDriverV2:default
