Feature/add dir and cactus services

added roles for directory and cactus service, cactus service is dependent to directory service, so should only need to specify directory service

• { role: roles/directory_service }

will get latest, optionally add a specific version

• { role: roles/directory_service, dir_srv_version: '0.1' }

after install you will need to

1. Set correct password in ldap.properties
2. Set correct password in wildfly data source cactus-ds which points to test cactus db by default
3. Enable the cactus service
