* Move Channels into App In this PR, we make Channels as part of App instead of Server. This is part of the transition period of moving fields from Server to Channels. For now, Channels contains Server. So the hierarchy is App -> Channels -> Server. And as a first step, we also move httpService to Channels. ```release-note NONE ``` * Fixing another test ```release-note NONE ``` * new method ```release-note NONE ```
