[ovn] devstack needs to support openflow15

Browse Source 
OVN has been changed to use Openflow15 [1].

Instead of creating br-int and setting the openflow version
via ovn_agent script, it is better to delegate the bridge
creation to the ovn-controller. Thus, having ovn-controller
creating br-int addresses the potential version mismatch.
