[Feature Request] Add a delay to hook

[Tsimopak]

Motivation: sometimes need to debug what happens in case of a race between different requests.

Hi @Tsimopak , I think this can be achieved by implementing a custom fetch function and adding a delay in it:

The fetch function has access to the entire request so you can determine when to inject the delay too. What do you think?
