Update namespace for RecursiveHotFileLoader in OpenStack Orchestration

[Dhamo1107]

Problem:

When attempting to create a stack in OpenStack using ManageIQ, the following error occurs:

uninitialized constant Fog::OpenStack::Orchestration::Real::Util

This issue is caused by a module naming mismatch in the fog-openstack gem.

Root Cause:

The code references Util::RecursiveHotFileLoader, but the correct namespace is OrchestrationUtil::RecursiveHotFileLoader.

Fix:

• Updated create_stack.rb to use OrchestrationUtil::RecursiveHotFileLoader instead of Util::RecursiveHotFileLoader.

This resolves the issue and ensures proper stack creation.
