[Chore] Refactor Storage Options

[ashika112]

Description of changes

During Gen2 storage work we made some changes to naming convention for types WithKey and WithPath. Seems like we missed to update a bunch of internal storage options type. This PR updates the types name.

• Also removes an unused s3 exception file

Note: All types updated are purely internal, no change to any external APIs
