Pacemaker support for OVN DB servers
This patch enables OVN DB servers to be started in master/slave mode in the pacemaker cluster. A virtual IP resource is created first and then the pacemaker OVN OCF resource - "ovn:ovndb-servers" is created. The OVN OCF resource is configured to be colocated with the vip resource. The ovn-controller and Neutron OVN ML2 mechanism driver which depends on OVN DB servers will always connect to the vip address on which the master OVN DB servers listen on. The OVN OCF resource itself takes care of (re)starting ovn-northd service on the master node and we don't have to manage it. When HA is enabled for OVN DB servers, haproxy does not configure the OVN DB servers in its configuration. This patch requires OVS 2.7 in the overcloud.
