This will let us pass a context.Context when creating a new request with getRequestFromEvent.

This will let us have a more granular control over how/when we cancel a request instead of relying only on the client timeout.

For example, if such API is invoked while serving another HTTP request, we might want to take advantage of such request context to bail out earlier than the client timeout if necessary.

As per documentation:

For outgoing client requests, the context controls cancellation.

For incoming server requests, the context is canceled when the client's connection closes, the request is canceled (with HTTP/2), or when the ServeHTTP method returns.
