Chore: Reduce 'six' usage

[iLLiCiTiT]

Changelog Description

As we moved from Python 2 we don't need to use six module anymore.

Additional info

Code where six module was used for Py2 and Py3 compatibility is not used anymore. There are still places where six is used but those are not as simple changes as these.

Replaced six.string_types with str. Instead of using six.add_metaclass is used ABC base class to define metaclass, or creation of class defines metaclass=... in creation. Replaced six.reraise with simple raise of exception, and some special cases are using different traceback.

Testing notes:

1. Go through code and validate the changes.

...I should maybe enable path to ayon-core in dev bundle.

[BigRoy]

Let me know if there's anything else to test.

• Launching applications works (Maya, Fusion, Houdini, Standalone Loader, Standalone Publisher)
• Updating containers works
• Loader works Fusion, Maya, Houdini
• Publishing works standalone publisher, Fusion, Maya
