What is the current behavior?
The resolver metadata cache currently uses the resolver name for the key as shown below
https://github.com/nestjs/nest/blob/39ec4cda7363aac3551ff0f1b83feb41ba2f0bf6/packages/core/helpers/handler-metadata-storage.ts#L60-L63
This causes issues if we have two resolvers in different modules but with the same name and identical method signatures. For controllers, each controller gets a unique ID that is used as the key in the cache as shown below:
https://github.com/nestjs/nest/blob/39ec4cda7363aac3551ff0f1b83feb41ba2f0bf6/packages/core/injector/module.ts#L461-L462
Add code to set up unique IDs for resolvers as well so that cache retrieval is correct.
Issue Number: #1907
What is the new behavior?
Each resolver gets a unique ID so that it can be retrieved correctly from the metadata cache. The solution re-uses the ID key that controllers also use so I worry that that may cause confusion.
