Story (Required)

As a QE, I want to verify addon tasks shipped with operator, similarly to cluster tasks.

Background (Required)

We have automated tests for shipped cluster tasks in https://github.com/openshift-pipelines/release-tests/tree/master/specs/clustertasks

Extend the test suite in release-tests repo to include tests also for ecosystem tasks + cluster resolver.

docs: https://github.com/openshift/openshift-docs/pull/77342

Approach (Required)

1. Create new test for the following tasks using a cluster resolver
2. Extend addon tests to check that disabling/enabling the addon works as expected
3. Add a new task to main pipelines - acceptance-tests, upgrade-tests and cluster-upgrade-tests

$ oc get task -n openshift-pipelines
NAME               AGE
buildah            6h14m
git-cli            6h14m
git-clone          6h14m
maven              6h14m
openshift-client   6h14m
s2i-dotnet         6h14m
s2i-go             6h14m
s2i-java           6h14m
s2i-nodejs         6h14m
s2i-perl           6h14m
s2i-php            6h14m
s2i-python         6h14m
s2i-ruby           6h14m
skopeo-copy        6h14m
tkn                6h14m

Additionally, we might consider removing original cluster resolver tests.
