The tripleo-ansible role for deploying multipathd [1] needs to be used as a basis for a similar edpm-ansible role. The tripleo-ansible role doesn't follow the "standalone" pattern (install, configure, run), so it will need to be adapted for edpm.

The dataplane-operator will need to be updated to invoke the new edpm_multipathd tasks.
