BUG REPORT

SUMMARY

I am running a DIY build of kubeaudit, slightly modified to run as a job within my k8s cluster.
To retrieve the results of the kubeaudit job I fetch all logs from the underlying pod.
The logs also include the warning introduced with PR 527, which is not affected by the --no-color flag.

ENVIRONMENT

• Kubeaudit version: 0.22.0
• Kubeaudit install method: DIY-BUILD

STEPS TO REPRODUCE

Run kubeaudit with --no-color flag.
For example: kubeaudit all --no-color --format=json

EXPECTED RESULTS

No color-codings in kubeaudit results as well as error and warning messages.

ACTUAL RESULTS

The color-coding for the "Unregistered Annotations" warning is still present.
Snippet of the logs:

time="2023-08-24T11:21:27Z" level=info msg="Running inside cluster, using the cluster config"
�[33m
[WARNING]: kubernetes.io for override labels will soon be deprecated. Please, update them to use kubeaudit.io instead.
