Motivation: At the moment we use a ByteBuf as the payload for a http2 frame. This complicates life-time management a lot with no real gain and also may produce more objects then needed. We should just use a long as it is required to be 8 bytes anyway. Modifications: Use long for ping payloads. Result: Fixes [#7629].
