Approach

What is the motivation for this PR?

Bullseye-based images currently have both a cronjob task and a systemd timer configured for the logrotate rotation. This can cause conflicts with two simultaneous log rotations happening (in the worst case; I think there's some check somewhere to prevent this from happening).

How did you do it?

To fix this, the cronjob task will be removed. This means that this file will no longer exist. Therefore, don't fail if this file doesn't exist.

How did you verify/test it?

Verified that KVM T0 part 1 tests pass with an image without /etc/cron.d/logrotate.

Any platform specific information?

Supported testbed topology if it's a new test case?

   the check by activating the python3 virtual environment in sonic-mgmt docker container or outside of sonic-mgmt
   docker container.
2. Ensure that the pre-commit package is installed:

sudo pip install pre-commit

3. Go to repository root folder
4. Install the pre-commit hooks:

pre-commit install

5. Use pre-commit to check staged file:

pre-commit

6. Alternatively, you can check committed files using:

pre-commit run --from-ref <commit_id> --to-ref <commit_id>

flake8 failures appear to be for lines I didn't touch. If needed, I can fix those issues as well.
