Delete request returns 200 but GCP returns 204

[Aranduran]

Environment details

• Programming language: Java
• OS: Linux
• Language runtime version: 11
• Package version: 0.54.0

Steps to reproduce

1. Call storage testbench with a Delete request to delete an object in the mock bucket. 200 response code
2. Call GCP with a Delete request to delete an object. 204 response code

This difference in response codes makes it harder to use this library to validate my application code. I have to account for 200 or 204 being returned, instead of just 204 which Google returns.
