Fix EDPM ovn update

In some topologies, for example Unidelta topology, nodeset include external ceph nodes.
Those nodes are not hosting ovn services. Update fails trying to run ovn update setep
on those nodes.

This patch improves creation of edpm-deployment-ovn-update.yaml file
to include only nodesets with ovn service enabled during initial deployment.

Closes: OSPCIX-738
