http2: refactor ping + settings object lifetime management
Have clearer ownership relations between the `Http2Ping`, `Http2Settings` and `Http2Session` objects. Ping and Settings objects are now owned by the `Http2Session` instance, and deleted along with it, so neither type of object refers to the session after it is gone. In the case of `Http2Ping`s, that deletion is slightly delayed, so we explicitly reset its `session_` property.
