Enable nose2 in Python Tests

[awolant]

Category:

New Feature

Description:

• Enabled nose2 in Python Tests.
• Added nose2 package to the list of packages installed in tests.
• Added nose2 configuration file to main Python tests directory. This file will be used to enable nose2 plugins.
• Created new directory operator in Python tests directory since nose2 can handle directory based tests discovery. We no longer have to depend on filtering tests names in bash scripts to run subsets of tests.
• One test file was copied to this new directory. Only changes to it were to remove unused code. Otherwise it is the same as the old test. Removed operator from the test file name since now it loves in operator directory.

Additional information:

Affected modules and functionalities:

Python tests and bash scripts related to how we run Python tests.

Key points relevant for the review:

Didn't I miss any test during the transition? Is everything that was tested with nose is tested with nose2.
