Bug 1658484

Summary:	OVN tripleo deployment should configure neutron config rpc_workers to a low number (1 is enough, and higher when using SRIOV)
Product:	Red Hat OpenStack	Reporter:	Daniel Alvarez Sanchez <dalvarez>

Fixed In Version:	openstack-tripleo-heat-templates-9.0.1-0.20181013060919.el7ost	Doc Type:	Enhancement
Doc Text:	This enhancement sets the number of RPC workers to `1` by default in OVN tripleo deployments. The goal of this setting is to reduce the number of workers to save memory resources and the number of connections to OVSDB, in cases where the Neutron DHCP agent is not deployed alongside OVN services.
