Bug 1878755

Description of problem:

The PHP image stream tag referenced by default cluster loader test is not present in OCP 4.5.

The image build and dependent deployment of clusterloader-cakephp will fail as the build configuration refers to an image stream tag (php:7.1) that does not exist in OCP 4.5. It's necessary to manually patch the build config to refer to an existing image stream tag tag (php:7.2) for the build to trigger and the deployment to run so that the default test can complete.

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

OCP 4.5
e2e test version: v1.18.3

How reproducible:

Always
[1] https://docs.openshift.com/container-platform/4.5/scalability_and_performance/using-cluster-loader.html

Steps to Reproduce:
1. Run cluster loader with default configuration as described in [1].
2. The image build of cakephp-mysql-example:latest will fail as the build configuration refers to a php tag that does not exist in OCP 4.5.
3. The cakephp-mysql-example deployment is stuck waiting for the cakephp-mysql-example:latest image that is never built due to the above error.

Expected results:

The test build configuration should refer to php:7.2 so that the cakephp-mysql-example build triggers automatically and the default cluster loader test completes.
