Drop static passwords

For security reasons, all passwords must be generated. That's why
all password related parameters has been moved to defaults but
commented out, so they will be required and one have to set needed
parameters if any of them used but missing, and also to have a reference.

Exclusions:
- `opencontrail_message_queue_password` must be defined due of
  limitations in OpenContrail over OpenStack
- `rabbitmq_guest_password` for backward compatibility
- `keepalived_openstack_telemetry_vip_password` for backward
  compatibility
- `gerrit_ldap_bind_password` for backward compatibility
- `opencontrail_identity_password` for backward compatibility
- `kubernetes_openstack_provider_cloud_password` for backward
  compatibility
