[ovs-dev] [PATCH v2 ovn 7/9] lb: link logical switches assigned for the same lb

[Lorenzo Bianconi]

As it has been already done for logical routers, add logical switches
datapath references in ovn_northd_lb data structure.
This is a preliminary patch to invert the logic used during the lb flow
creation in order to visit lb first and then related datapath.
