Unable to set Controller and ComputeIHA Parameters

Issue

• We have been trying to set the following in code, but they don't get reflected to correct cinder.conf and nova.conf files :

parameter_defaults:
  ControllerOpenstackAndNetworkerParameters:
      cinder::rpc_response_timeout: 1800 (defaults to 60 after overcloud deploy)

  ComputeIHAParameters:
    nova::block_device_allocate_retries: 1800 (this will be removed after overcloud deploy)
    nova::block_device_allocate_retries_interval: 3 (this will be removed after overcloud deploy)

  ComputeExtraConfig:
    nova::compute::cpu_allocation_ratio: 1.0 (defaults to 16 after overcloud deploy)
    nova::compute::ram_allocation_ratio: 1.0 (this one works, probably 1.0 is the default)

• We can see the rpc_response_timeout value was left unchanged:

(undercloud) [stack@director ~]$ ansible -i ~/overcloud-deploy/${STACKNAME}/tripleo-ansible-inventory.yaml ControllerOpenstackAndNetworker -m shell -b -a 'crudini --get /var/lib/config-data/puppet-generated/cinder/etc/cinder/cinder.conf DEFAULT rpc_response_timeout'
