Kiota produces large OpenAPI documents even when only one endpoint is selected because it doesn’t remove unused components.

Client library/SDK language

None

Describe the solution you'd like

When generating plugin and clients, Kiota should be able to trim unused components from the original OpenAPI document to generate a clean sliced OpenAPI document with only the information that is important for my solution.

For clients:

• Remove all unused components and keep all used components including schemas, parameters, responses.
• Remove all extensions (starts with x-) that don't match with our internal documentation of supported extensions in Kiota.

For plugins:

• Removes all unused components and keep only schemas and parameter of used components. For plugins we should also remove any responses components as this won't be used by orchestrators and can increase the size of the OpenAPI document.
• Remove all extensions (starts with x-) that don't match with our internal documentation of supported extensions in Kiota.
