move E2E tests into konflux.

we have to separate test suites; one in jenkins (runs daily), and another in repo workflows (runs upon PR events or merges to trunk).

for jenkins jobs, as a first phase, we can trigger them from a konflux test-integration.
later we can migrate the job entirely to run from within konflux.

GH actions will have to migrate entirely.

here are some details provided by the konflux users help forum:

generally:

• the basic integration-test 'enterprise-contract' was a required part of the initial migration (as described in the console-dot guide)
• migrating any other (custom) integration-tests depended on whether their system is considered legacy or not:
  • tests in github actions, like our PR/push E2E suites, can remain as-is, but are recommended to migrate at some point
  • tests in jenkins jobs, like our daily E2E smoke-tests, can be considered legacy and as such were advised to migrate ASAP (but were still not blocking for initial migration)
• whether a system is considered "legacy" should be verified with the specific system owner (in our case i think app-interface own the jenkins instances we're using, so we should contact them to get a definite answer)

specifically for our jenkins daily smoke-tests suite:

• migrating any build jobs used by tests was mandatory for initial migration (like cypress container image builds – see OCMUI-2312)
• migrating test execution was not strictly mandatory, but recommended, to benefit from release gating and better performance (hence this epic was opened and split from the main epic – OCMUI-2236)
• migrating the trigger was mandatory – i.e. even in the case of running our suite from within a jenkins job and not a konflux test scenario, we needed to move to using a konflux integration-test to call the jenkins job
