Thanks a lot @CiprianAnton!
Let's just pin traitlets<5.2.0 for now, until ipython/traitlets#736 is fixed.

In case an error happens in
start_channels(), the kernel is never cleaned up, leading to leaks. For e.g., inGatewayKernelClientthere is a chance we getConnectionError.Another place to ensure cleanup is in
setup_kernel, however, sinceasync_start_new_kernel_clientalready performs cleanup in case of timeout, I think it's a better fit here.Added test to cover this. All tests passed locally.
