Cloudflow operator crashes when it handles very large stream of k8s events.

[RayRoestenburg]

Describe the bug
The cloudflow-operator (version 2.0.5) crashes with an error:
2020-07-24 12:20:23,057 ERROR [Materializer] - [app-event] Upstream failed.
akka.http.scaladsl.model.EntityStreamSizeException: EntityStreamSizeException: incoming entity size (while streaming) exceeded size limit (67108864 bytes)! This may have been a parser limit (set via akka.http.[server|client].parsing.max-content-length), a decoder limit (set via akka.http.routing.decode-max-size), or a custom limit set with withSizeLimit.

Even though the limit is set to 64MB.

To Reproduce
Hard to reproduce, since you need a serious amount of events in a kubernetes cluster.

Expected behavior
The cloudflow-operator should use chunks and not get into entity size issues, as long as every single entity does not exceed the limit:
https://kubernetes.io/docs/reference/using-api/api-concepts/#retrieving-large-results-sets-in-chunks
Also see doriordan/skuber#258 for a known issue in skuber. We'll need to use the limit and continue options in skuber or create a PR on skuber to do this automatically.

Fixed by not setting a limit for entity size #908
