We need to enhance the plugin generation process in Kiota by implementing validation rules. These validations will ensure that the generated plugins function correctly.
Some of these validations address current limitations that may be resolved in the future. However, it is crucial to ensure that the generated plugins work with the current constraints.

Requirements

• Requirement 1: Validate all the above rules before generating a plugin and only generate the plugin if there are no issues.
• Requirement 2: Warn the user if their OpenAPI is not valid for plugin creation and don't generate the plugin
• Requirement 3: Inform the user which selected endpoints are failing validation and the specific reason. For example, one has 10 endpoints selected to create a plugin and just 1 fails due to nested objects in the PUT method; notify of the specific endpoints and the reason for the failure.
