Python 3.12 dropped distutils

[d0b3rm4n]

Describe the bug
See PEP-0632 Python 3.12 dropped distutils.

Steps to Reproduce
Steps to reproduce the behavior:

python --version
Python 3.12.3
pip install robotframework-reportportal robotframework
post_report
Traceback (most recent call last):
  File "/.pyenv/versions/bugreport/bin/post_report", line 5, in <module>
    from robotframework_reportportal.post_report import main
  File "/.pyenv/versions/3.12.3/envs/bugreport/lib/python3.12/site-packages/robotframework_reportportal/post_report.py", line 50, in <module>
    from robotframework_reportportal.result_visitor import RobotResultsVisitor
  File "/.pyenv/versions/3.12.3/envs/bugreport/lib/python3.12/site-packages/robotframework_reportportal/result_visitor.py", line 22, in <module>
    from . import listener
  File "/.pyenv/versions/3.12.3/envs/bugreport/lib/python3.12/site-packages/robotframework_reportportal/listener.py", line 29, in <module>
    from .service import RobotService
  File "/.pyenv/versions/3.12.3/envs/bugreport/lib/python3.12/site-packages/robotframework_reportportal/service.py", line 31, in <module>
    from .variables import Variables
  File "/.pyenv/versions/3.12.3/envs/bugreport/lib/python3.12/site-packages/robotframework_reportportal/variables.py", line 16, in <module>
    from distutils.util import strtobool
ModuleNotFoundError: No module named 'distutils'

Expected behavior
Either dependency to distutils is removed or a dependency to setuptools is added since that ships distutils and command runs without problems.

Actual behavior
See stack trace above.
