As with Cloudflare we create a new client on every request, that means that every integration that uses an
addHandlerand is used by the Cloudflare SDK is makes the client not disposable - so the garbage collector can't remove it properly.This PR adds a callback for
addHandlerthat basically removes the handler from the global handler array (for now only for integrations, which are used by the Cloudflare SDK). I actually also tried to change the global handler to be aWeakMap, but it still showed some memory leaks with that, so we need to actively remove these callbacks.For now, to not increase the bundle sizes for core too much, it is actually removing the handlers only in the
ServerRuntimeClient, as for browsers it is usually not really an issue.
