In vmware-nsx lbaas service folder, the base_mgr module can be shared between nsxv and nsxv3. Thus move it under lbaas folder so it can be use by nsxv3 as well. To have minimum impact on nsxv side, rename base to LoadbalancerBaseManager and subclass EdgeLoadbalancerBaseManager from it. Also, this patch fixes a few pep8 error.
