PR Summary

This small PR resolve the deprecation warnings of daemon for threading methods:

/home/runner/work/polyaxon/polyaxon/cli/cli/polyaxon/_client/workers/base_worker.py:34: DeprecationWarning: setDaemon() is deprecated, set the daemon attribute instead

We are still supporting some older versions of python, so we can't merge this yet.

@mmourafiq I believe the change from setDaemon(True) to directly setting the daemon property (thread.daemon = True) was introduced in Python 2.6. Does the project still support Python 2.5 and earlier? See more information here. Looking into the setup.py file, It looks like the minimum Python version supported by this polyaxon/cli is Python 3.8.
