Add upgrade test and admin testing in CI

[lumtis]

Add a test that can be run in the CI for:

• Upgrade tests (run with make stateful-upgrade-source) test the upgrade from previous release to the current branch
• Admin tests (instruction for it to be documented in Write complete E2E and localnet testing documentation #1612), test admin functions, not currently tested in default E2E tests as it normally tested very scoped functionalities.

These tests shouldn't run each PR since long and scoped, solution:

• Add the ability to manually run those when needed
• Add these tests as part of the release CI workflow
• Run these tests automatically periodically.
