Replacing kernel spec variables for arg and env that are in kernel.json on values from custom_kernel_specs parameter which is configured by a user. custom_kernel_specs is passed from Jupyter Lab through jupyter_server.
Clearing kernel spec variables that are in kernel.json if they are present into this file but custom_kernel_specs parameter is missed
Adding basic validation to check whether custom_kernel_specs does not include anything wrong
Adding support if a kernel.json file includes customization for a kernel but a user has not selected anything then a parameterized kernel will be run by using default values from its kernel.json file
