jupyterlab-sos depends on display name of kernel

[BoPeng]

kernel-dropdown is not displayed for sos kernels with a different display name.

The problem has been partially resolved. More specifically, jupyterlab-sos can now handles non-SoS displayed name, but the kernel name has to be sos for jupyterlab-sos to recognize the sos kernel. That is to say,

• Kernel my_kernel with displayed name SoS will no longer works, but
• Kernel sos with name My SoS will work

Ideally, jupyterlab-sos should recognize the kernel by “language”, not by kernel name or displayed name. Unfortunately, jupyterlab does not know the “language” information when the kernel is started so jupyterlab-sos has to guess the language either from kernel_name or display name. I will keep the ticket open and see if there can be a better solution.

Listening to promise context.sessionContext.session?.kernel?.info helped. I need to hide the language dropdown by default, and enable it only for sos kernels to avoid setState for ReactWidget, but this should be the way to go anyway.
