dfdec92c6e Use ping option only for DCP WebSocket 
* The Faye::WebSocket library will "buffer" some output of the connection and emit the `on :message` events in the order of the messages. However, when a ping is sent while the connection has already been closed, it will emit the `on :close` event immediately and drop all other messages (in that "buffer"). This is problematic for very short running executions that generate a long output (as this will be cut off without a proper exit message sent by Poseidon).

4f1a7cde27 Add null strategy for runners 
* This is the default strategy used when the runner management is disabled. It might be replaced with a generic Docker strategy in the future (without pooling). For now, it allows normal "operation" of CodeOcean without any runner management. However, as no runner system is configured, no command can be executed.

87c5302336 Switch logging to milliseconds and add more details 
* By design, most logging happens in an `ensure` block. This ensures that no return value is modified unexpectedly.

9e2cff7558 Attach connection errors to socket 
Raising the errors would crash the current thread. As this thread
contains the Eventmachine, that would influence other connections
as well. Attaching the errors to the connection and reading them
after the connection was closed ensures that the thread stays
alive while handling the errors in the main thread of the current
request.
