Fix Jenkins Job to build and deploy nightly images

[ricardozanini]

Describe the bug

Currently, Apache Jenkins has not been working since the migration from kiegroup. After an initial assessment, we need the following:

1. Remove OpenShift tests since we don't have a cluster yet (we may add this later once we have a cluster to run)
2. Assess the tooling to build the operator image in the current infrastructure
3. Change the build stage to use the tooling we have in Apache Jenkins

Expected behavior

kogito-serverless-operator-deply job to work on Apache Jenkins: https://ci-builds.apache.org/job/KIE/job/kogito/job/main/job/nightly/job/kogito-serverless-operator-deploy

Actual behavior

See description.

Now we get an other error:

ERROR: Could not find credentials entry with ID 'OPENSHIFT_API'

[ricardozanini]

I still see problems, now with a free local port in the registry.

Today the failure was the E2E tests execution:
https://ci-builds.apache.org/job/KIE/job/kogito/job/main/job/nightly/job/kogito-serverless-operator.e2e.minikube/1/console

I am looking into that, looks like E2E failed when starting minikube

after #323 and #349 the nightly builds are working well.
