Kf 4075 feat unit tests for jupyter pytorch cuda full rock

[i-chvets]

Unit tests for Jupyter Pytorch Cuda Full ROCK. These tests verify that all artefacts are in place, that imports can be made in mounted/executed Python script, and that Jupyter Notebook Server is accessible.

Summary of changes:

• Tests for testing ROCK integrity.
• Commented out some imports in import test as TO-DOs to be addressed during integation stage. Those might not be required to be tested as importes. Integration should verify this.
• Changed /home/jovyan to be owned by daemon
• Added notebook server access test.
• Added unit test to test artifacts, imports, and access.
• Added tox.ini

Testing:

tox -e unit
