Make empty body configurable behaviour

[CezaryBD]

Expected Behavior

It should be configurable if fail or pass the response.

Actual Behaviour

https://github.com/micronaut-projects/micronaut-core/commit/ab5c4a244b25113d06378771bd43dfa7db7c29bc#diff-af18b3b8347409fdb81dedda7689f9d13c962d129830818e2dbd4c48770ddecdR151 Line #166. This change introduces a default behaviour that I would prefer to be configurable. An empty body on 200 OK status is not an error :)
