Conda environments without Python are not displayed in the Kernel Picker

[DonJayamanne]

Scenario:

• User creates a new conda environment (without Python, this happens when users do not provide python version info)
• User opens a notebook and goes into kernel picker and this new conda env isn't in the list
• However this conda env is in the list of python interpreters

Note:

• The new conda env is listed in list of Python interpreters in the Python extension
• Upon selecting this interpreter Python extension will install python into this conda env

Suggestions

• Display this kernel in the kernel picker
• Upon selecting this conda env from the kernel picker do what Python extension does today (via a Python extension API)
