docs: added a service factory reference (#8292)

Added a service factory reference of the generated methods and how to use them.

Since the types in the codebase are a bit complex, a generated reference won't provide a valuable result.

Instead, this reference is created manually and aims to cover common use cases, providing examples for them.

Closes DOCS-844
