LOG_LISTENER_FLAGS bypass flags for the on-device log_listener
Creates an SSH connection with a device and starts listening for logs.
It will listen to the device specified with `fx -d DEVICE log` or
`fx set-device`, otherwise it will try to find a connected device.
For more information on flags supported by on-device log_listener, look at
