Bug 1537471

Description of problem:
-----------------------
default_volume_type for cinder is not set. And based on description from /etc/puppet/modules/cinder/manifests/api.pp:
 (optional) default volume type to use.
 This should contain the name of the default volume type to use.
 If not configured, it produces an error when creating a volume without specifying a type

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
puppet-cinder-10.3.1-1.el7ost.noarch
openstack-tripleo-heat-templates-6.2.1-2.el7ost.noarch


How reproducible:
-----------------
100%


Steps to Reproduce:
1. Deploy RHOS-11, e.g:
openstack overcloud deploy --templates /usr/share/openstack-tripleo-heat-templates \
  --stack overcloud \
  -r /home/stack/composable_roles/roles/roles_data.yaml \
  -e /home/stack/composable_roles/roles/nodes.yaml \
  -e /home/stack/composable_roles/roles/network-config.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml \
-e /home/stack/composable_roles/internal.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
-e /home/stack/composable_roles/network/network-environment.yaml \
-e /home/stack/composable_roles/enable-tls.yaml \
-e /home/stack/composable_roles/inject-trust-anchor.yaml \
-e /home/stack/composable_roles/public_vip.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/tls-endpoints-public-ip.yaml \
-e /home/stack/composable_roles/debug.yaml \
-e /home/stack/composable_roles/nova-disable-versioned-notifications.yaml

2. Check default_volume_type value in cinder.conf on controller


Actual results:
---------------
default_volume_type is not configured

Expected results:
