Convention suggestions

These are some of the conventions that were observed to give better results, but they are by no means definite and any suggestions are welcome.

• Prefix workflow and task names with the domain they are dealing with. Since conductor is a microservice orchestrator different teams might be naming them and it is easy to create name conflicts if you stick to names like validate_input.

• Use validation attributes for request model properties to make the handle method lighter.

• Keep request and response models in the same file with the worker if you plan on having a lot of workers. This is usually not good, but the number of files can make the project hard to navigate.
