Right now the Kogito operator e2e tests run against local operator code only.
However this configuration doesn't provide much flexibility as tests have to be executed sequentially. Considering that every test can take easily 10 minutes or even more this becomes unbearable for running larger number of tests.

By allowing to run tests against external image we will be able to run tests in parallel, using OpenShift capabilities to much more extent, reducing test suite execution time.

This JIRA is addressing possibility to run e2e tests with external operator image.
