Summary:
Implemented ConnectionCloseEvent interface for QLogger. As part of spec, [see here.](fburl.com/qlog-schema)
I intend to add this to ProxygenQLogger after [D15945914](https://our.intern.facebook.com/intern/diff/D15945914/) lands, and connect it to Quic in the next diff (ex. `qLogger->add...`).

Summary: Rename `add` to `addPacket`, since `add` is an ambiguous function name, especially as we include more events.

Summary:
Refactor QLogger to include derived QLogger classes depending on use case.
The QLog output will differ depending on what is requesting a QLog.
`File QLogger`: This is connected to HQ, stores all of the events per connection, and then outputs them to a file.
