Fixed some class names that were in snake_case because
it's not right according to PEP8/PyLint. Now they're all camelCase.
Also, did a direct assignment to client_manager attributes.
Test Plan:
PASS: Run tox command.
- pylint success
- pep8 success
- py39 success
PASS: Check if all commands are working properly.
