Bug 2081678

Description of problem:

Starting with OpenShift Container Platform 4, ANSI color support was added in the OpenShift Container Platform 4 - Console (see https://github.com/openshift/console/pull/10486)

This works well, until an application does not end ANSI color modification with `\e[0m`. If that is not done logs from other pods will show the ANSI color modification from the last line that had it specified, even when those pods don't define ANSI color code.

The above pod is missing `\e[0m` at the end of `echo -e "\e[0;35mPurple"` meaning `echo -e "No coloring"` will also be purple (which sort of can be expected). But when now moving to `openshift-ingress` `namespace` in the OpenShift Container Platform 4 - Console and watching `router` logs, they also show purple, even though the `router` does not have ANSI color modification in the logs.

This pod has the expected `\e[0m` at the end of `echo -e "\e[0;35mPurple\e[0m"` and shows the expected behavior. Also no carry over of ANSI color modification to other pods.

Version-Release number of selected component (if applicable):

 - OpenShift Container Platform 4.10.9
 - OpenShift Container Platform 4.11.0-0.nightly-2022-04-26-181148

How reproducible:

 - Always

Steps to Reproduce:
1. Install OpenShift Container Platform 4.10 or later
2. Create the pod as shown below

> apiVersion: v1
> kind: Pod
> metadata:
>   name: coloring
>   labels:
>     purpose: coloring
> spec:
>   containers:
>   - args:
>     - -c
>     - |
>       # trying color scheme
>       echo -e "\e[31mRed Text\e[0m"
>       echo -e "\e[42mGreen Background\e[0m"
>       echo -e "\e[0;35mPurple"
>       echo -e "No coloring"
>       sleep 9999
>     command:
>     - /bin/bash
>     name: color-container
>     image: registry.redhat.io/ubi8/toolbox:8.5
>   restartPolicy: OnFailure

3. Access it's log in the OpenShift Container Platform 4 - Console and validate that after `Purple` output all following lines are colored `Purple`

4. Move to `openshift-ingress` `namespace` and inspect `router` logs which will also show up `Purple`

Actual results:

If ANSI color modification is not ended, the last color code is carried over to the next pod logs

Expected results:

No carry over of unfinished ANSI color modification to other pods and potentially forcefully end ANSI color modification if not specified.
