Refactor ovn_bgp_agent.privileged.ovs_vsctl
When ovs commands fail, we re-try after adding `-O OpenFlow13`, but that is only valid for `ovs-ofctl`. To fix this issue, this patch implements a small refactor of the module in order to separete calls to ovs-ofctl and ovs-vsctl. Related-Bug: #2080258 Change-Id: Ib8ee872d4bd587ade325bc4f6da3e9d8804c28c0
