Required Changes
- Knox will parse referenced provider configurations, rather than just blindly copying their contents.
This will serve multiple purposes:- It will provide a degree of validation (invalid provider configurations would fail parsing)
- It will allow a finer level of control over what is serialized to the generated topology file:
- Knox will have the opportunity to add cluster-specific details into provider configuration in the generated topologies
- Knox could reference elements of the provider configuration (e.g., HaProvider) to inform the generation of service elements in the generated topologies.
