Use role instead of playbooks - validations.yml

Before simplifying 06-deploy-edpm.yml, it is necessary to take care of import_playbook calls within that play

There are three import_playbook calls within 06-deploy-edpm.yml
- validations.yml
- nfs.yml
- ceph.yml

This PR takes care of validations.yml

It is continuation of simplification job execution [1].
