Story (Required)

As a developer trying to release Jenkins for Openshift 4.15 I want the base images to be based on RHEL9.

Background (Required)

The Jenkins build scripts are using RHEL8 as base builder image. To release Jenkins images with HoneyBadger for Openshift 4.15 and later, the base image needs to be updated to RHEL9

Out of scope

<Defines what is not included in this story>

• Plugin updates related to CVE fixes

Approach (Required)

Change the build scripts and other references of RHEL8 to RHEL9

1. Update image bases in upstream to use UBI9 (github.com/openshift/jenkins)
2. Update CPaaS configuration to use equivalent UBI9 image bases mid/downstream.
