Creates an SSH connection with a device and starts listening for logs. It will listen to the device specified with `fx -t DEVICE log` or `fx set-device`, otherwise it will try to find a connected device. If the command hangs without printing anything, first check to make sure `fx shell` works on its own. For more information on flags supported by the on-device log_listener, see https://fuchsia.dev/fuchsia-src/reference/diagnostics/consumers/log_listener.
