Discuss webhook implementation standards & alignment with industry leaders

[dutabado]

From Convoy internal review:

Can/should we attempt to align our webhook implementation with folks in the industry trying to make them easier, e.g. Svix, Hook0, etc?

Additional option from OneNetwork call - consider using some sort of nonce / token / etc that can be rolled on a specific interval, e.g. every callback responds with a new callback URL that has a new nonce for the next callback to use

I think we are past the point of making changes here for v1. We should tag this with a new future-enhancement label for easy discovery when discussing future versions and close for now.
