Reduce ValidationHook requests

[doddi]

Is your feature request related to a problem? Please describe.
When making use of the ValidationHook configuration a module is validated against multiple times, one for each file request such as .mod, .info and .zip. Validating a module multiple times is unnecessary and could put a burden on the endpoint doing the validation.

Describe the solution you'd like
The validation endpoint is used only once per module request.

Describe alternatives you've considered
The validation endpoint provides extra information (header or body) describing the reason for the validation (info, zip, mod) and the endpoint could make the decision on whether to ignore the request.

@doddi sorry for the long delay. I don't see a reason why we shouldn't do this. I'll assign myself and send a PR as soon as I can. If you'd like to do it before me, just comment here and it's all yours 😄

Hope you have a good weekend!

@arschles How would you propose we solve it? Is it as easy as sending the validation hook only when requesting .zip? or do you think there is a better approach

I don't see a reason why we shouldn't do this

@doddi I should have been clearer here 😆. what I mean to say is, I think we should do this as you suggested in the OP 😄

@arschles Im happy to take a look at this if you want to assign it over
