CI/CD docker artifact repository needs to be removed from current location to something else.

Describe the issue you're reporting

When this project was donated to the open source community by Splunk, we have used Splunk's quay.io repository which is going to be shutdown soon due to security issues. We had agreed the CI/CD artifacts needs to be moved to a public artifacts repository sooner than later. if not removed the CI/CD won't function properly.
