This change will work exactly as your request.
There is only one python library path to be added.
1. If the user does not install python via conda.
(If the user installs only the library)
Zeppelin use to `zeppelin.python`.
(Used in the original environment.)
2. If you install python via conda.
(separate python from zeppelin.python)
if when the conda environment is active, add to library path and replace to
installed python via conda from zeppelin.python.
Zeppelin to work in the new python environment.
3. The user disables the environment. (conda deactiavte)
It is restored to the original zeppelin.python environment.
